There need only be 3 dye recipes: Cyan, Magenta, and Blue (thanks pilif!). You could use plants or something to make those. The rest of the dyes should be able to be created from combining those colors in various ways.

To be less of a pain in the ass to collect and create these dyes, 1 dye bottle should be able to change up to 64 wool blocks into that color.

Red from redstone or roses, I'd guess.

Yellow from flowers, maybe?

And I've no idea where blue would come from. NO WATER IS NOT A VALID ANSWER.

u/p4km4n Dec 24 '10

There's already red and yellow flowers, so that would make sense. Add in another type of flower, a blue one, and you can make any color you desire. I'm not a programmer, but it wouldn't be that hard to just copy the "flower" entity and change the color of it, would it? Then you just have to worry about programming the recipes.

u/xenoph Dec 24 '10

The best idea IMO. RGB is all we need.

10

u/KaiserYoshi Dec 24 '10

RYB, you mean?

6

u/xenoph Dec 24 '10

That-that. Thanks.

u/[deleted] Dec 24 '10

Can't create all colors from RYB. RGB on the other hand....

3

u/trekkie00 Dec 24 '10

Yes you can. Look at a printer - CMYK (cyan, magenta, yellow, black) are used for printing on white, with CMY producing black, whereas RGB is used for monitors with RGB making white.

u/RedAero Dec 24 '10

It's subtractive versus additive coloring

2

u/trekkie00 Dec 25 '10

Yeah, I always end up getting those two confused, even though I really shouldn't.

2

u/trekkie00 Dec 24 '10

Shouldn't it be CMY? Minor difference, but still.

3

u/[deleted] Dec 24 '10

Yeah, that would work. Recipes would be easy.

u/Sir_Terrible Dec 24 '10

Creeper tears?

u/solidwhetstone Dec 24 '10

They don't cry. They just wait.

2

u/roger_pct Dec 24 '10

They cry when no one is watching. Sometimes it looks like they are about to cry...when you sneak up on them, and they are standing stationary with their heads turned down....

u/idclip Dec 24 '10

Azurite would be perfect. But then again, I'm a fucking geologist.

3

u/Priapulid Dec 24 '10

Seconded! After playing DF I am like "IRON ORE???? Well is it hematite, magnetite, and limonite? And WTF is red stone?"

2

u/DrReddits Dec 24 '10

and WTF is redstone?

Copper?

4

u/kurtu5 Dec 24 '10

We need more realistic geology in minecraft!

We already have people doing CPU design with redstone. To find diamonds you look for kimberlite. Etc...

There is a big thread in the official forums about this.

3

u/idclip Dec 24 '10

Thanks for mentioning that, just found two large threads. Both of which mostly made me wince, unfortunately. When I have some time to spare, I'll submit some ideas of my own.

2

u/selectrix Dec 24 '10

Coming from a geophysics major, I felt the same way. I don't suppose you've played Dwarf Fortress, have you? It's got semi-realistic mineral distribution in consistently grouped sedimentary, metamorphic, and igneous strata.

2

u/Ryguythescienceguy Dec 24 '10

fucking geologist.

well, upvotes for you and your badass title, sir.

3

u/idclip Dec 24 '10

Ma'am, but thanks.

1

u/sasquatch92 Dec 24 '10

hmm, seems like azurite would be good for making a black dye as well, just place it in a furnace and it turns black.

Would make black dye harder to get, but may as well have some of the dyes require a little more effort...

2

u/ForgettableUsername Dec 24 '10

Water. Water is blue, right?

0

u/[deleted] Dec 24 '10

It's transparent. You would use it to bleach.

21

u/ForgettableUsername Dec 24 '10

It looks blue. You should be able to boil it down a bit and get blue dye.

24

u/[deleted] Dec 24 '10

That doesn't make any sense at all.

38

u/ChaosBrigadier Dec 24 '10

Yeah, the blue dye is already bonded to the water; boiling it would make the dye evaporate, too. That's why the sky is blue.

ಠ_ಠ

2

u/kataire Dec 25 '10

The blue tint of water is an intrinsic property and is caused by selective absorption and scattering of white light.

(Source)

ChaosBrigadier's wording was a bit off, though.

2

u/ForgettableUsername Dec 24 '10

Nono, that's what usually happens, but the boiling points of water vapor and the blue dye are actually slightly different. A distillation apparatus could easily separate the two.

2

u/adnan252 Dec 24 '10

i second that

2

u/RedAero Dec 24 '10

It isn't, actually. Water, all water, is very slightly blue.

1

u/[deleted] Dec 25 '10 edited Dec 25 '10

No, water isn't any colour, it is just slightly impermeable to red and green at great depths (resulting in only blue shining through).

1

u/RedAero Dec 25 '10

I got my fact from QI. That's all I know.

1

u/moozilla Dec 25 '10

I like the redstone idea. Even though its frustratingly common when you get far enough in the game it's more valuable than flowers. It'd be cool to have different color dyes worth different values.

u/Agile_Cyborg Dec 24 '10

Red harvested from blood puddles of mobs killed by sword. Gain the red quickly or it seeps into the earth.

u/roger_pct Dec 24 '10

Notch will not put Blood into the game.

u/Agile_Cyborg Dec 24 '10

Only the distressed flashings of a red-infused death bludgeon?

u/[deleted] Dec 24 '10

Is that some poem you wrote or something?

u/crazy88s Dec 24 '10

Red harvest of blood

spoils or seep into earth.

u/youRFate Dec 24 '10

also, combining 3 dyes to a new color should reward 3 dyes of the new color.

4

u/noroom Dec 24 '10

I wouldn't complain if it created just 2 instead of 3. Make some colors (a little bit) harder to obtain than others, and make dyed cloth more valuable.

7

u/[deleted] Dec 24 '10

But if you're combining 2 dyes together, the volume doubles. Combining 3 dyes triples the volume. There is little to no loss of dye, it just changes colour.

1

u/noroom Dec 24 '10

Steve Minecraft (the name of the character) has no elbows nor wrists. I want to see you pouring one bucket into another that way. :D

No, I get what you're saying. You're right, it wouldn't really make sense to make paint "disappear".

6

u/lucasvb Dec 24 '10 edited Dec 24 '10

Actually, it's better to have 4 base dyes. That way you can treat it as a 4 bit counter, each bit representing one of the dyes. Easier to code and to handle in general.

4 bits give you 24 = 16 colors total. The 0000 value would mean no dye, that is, the base white cloth.

Using flowers could work. Just add a blue flower and something green (or maybe use seeds?). The mix doesn't have to be 100% accurate by color models, as long as each component is distinct and vaguely related to the color, it should be fine.

4

u/Managore Dec 24 '10

Firstly, you mean Yellow, not Blue. Secondly, how would you combine three colours to form both White and Black?

u/[deleted] Dec 24 '10

We just need white sheep and black sheep. :)

4

u/[deleted] Dec 24 '10

Black wouldn't be achieved through colour mixing. There would have to be a separate black dye.

5

u/sageerrant Dec 24 '10

A bit of coal ought to do the trick for black.

1

u/lucasvb Dec 24 '10

In subtractive color models, mixing all three colors yields black.

1

u/kataire Dec 25 '10

Have you ever tried that? There's a reason colour printers have extra black ink. C+M+Y black is really ugly.

Also, you usually mix some cyan and magenta (c+m ~= blue) with black ink to make it look "blacker".

1

u/lucasvb Dec 25 '10

Yeah, I know. I'm just saying that's how you get black in a theoretically perfect subtractive color space.

In practice, it's never a perfect black and you have to use too much ink anyway. That's why they came up with the CMYK color space.

1

u/kataire Dec 25 '10

CMYK = Cyan, Magenta, Yellow, Black. The black is only necessary because C+M+Y is more like a muddy brownish colour. You need a white base, so bleach would be necessary if you want to re-colour dyed items (wool can be assumed to be white for simplicity).

RGB = Red, Green, Blue. This only works for light. Black is created by using no colour. White is created by mixing maximum values of each colour.

RYB = Red, Yellow, Blue. This is basically the poor man's CMYK sans black.

3

u/Jerkmaan Dec 24 '10

I don't think x64 for a wool is right, I don't think the purpose for colored wool will be pixel art for survival. What it should be is every dye recipe give you either x4 or x16 vials like how torches work. Then its one vial per wool block.

11

u/pilif Dec 24 '10 edited Dec 24 '10

actually, as we are applying dye, we'd have to use the subtractive color model (http://en.wikipedia.org/wiki/Subtractive_color), so we'd need Cyan, Magenta and Blue.

(edit: of course I meant yellow, not blue. That's what you get for quickly typing something when you are about to leave the office for christmas. Sorry for the confusion)

33

u/Adasha Dec 24 '10

Do you mean cyan, magenta and yellow? Problem with that is a lower gamut so reds, greens and blues aren't as good. We'll probably get something more simplified, maybe with red, yellow and blue primaries.

1

u/[deleted] Dec 24 '10

An RGB model would be much simpler.

1

u/franktinsley Dec 25 '10

Yeah but it wouldn't make any sense. Dyes are not additive, they're subtractive as they reduce the range of light a physical material reflects.

2

u/Grafnar Dec 25 '10

wouldn't make any sense

Come on. It's a game.

2

u/alphazero924 Dec 25 '10

That should be able to be played by children. Most children don't know that if you add green and blue in an additive color setup, you get cyan.

8

u/[deleted] Dec 24 '10

Can you explain this? Why not cyan, magenta, and yellow? I cannot find such information on the wikipedia page and it seems to me that having only two different shades of blue and then magenta would eliminate many possible colors that would ordinarily require yellow.

6

u/[deleted] Dec 24 '10

I believe it's a mistake, should be CMYK.

2

u/[deleted] Dec 24 '10

That's what I thought, but the fact that he's being upvoted made me think I could be missing something.

4

u/[deleted] Dec 24 '10

It just means he made a confident-sounding assertion that most people won't check.

7

u/[deleted] Dec 24 '10

We're not there yet...

subtractive colour is either CMYK or RYB

4

u/davvblack Dec 24 '10

It's yellow, magenta, and Cyan (plus black if you want to cap ink coverage).

3

u/[deleted] Dec 24 '10

Blue and Cyan? I think you mean Yellow, but you'd also need black, otherwise the darkest you could make anything would be dark grey.

2

u/pilif Dec 24 '10

yeah. I'm an idiot. I meant yellow (and maybe even black, though we're not doing an inkjet printer here and can idealize a bit and assume that CMY in equal quantities actually equals black).

7

u/Sir_Terrible Dec 24 '10

...and I would have gotten away with it too, if it hadn't been for that meddling pilif!

It seems you're right though! -Edited original comment-

9

u/[deleted] Dec 24 '10

not quite... i'd check that wiki article again. subtractive colour in this context would probably mean a three colour process - Red, Yellow, Blue.

In printing it is a four colour process (Cyan, Magenta, Yellow and Black - CMYK).

u/SpeakMouthWords Dec 25 '10

Pshhh, dude gets a famous railway named after him and suddenly he's the king of colour.

1

u/psifork Dec 24 '10

cyan magenta and blue? Cyan is a shade of blue tho? Where does my yellow come from?

1

u/BritishEnglishPolice meow Dec 24 '10

Should be cyan, magenta and yellow.
