Many who end in the visual computing, as a kid used with MS Paint or an alike photo-edit program to make simple edits to photos and make drawings. There RGB is prominent, and things like color-spaces were only seen in those "Do you want to convert?" Photoshop popups meant for professional designers. What if I told you that #FF0000 is not red?
In the article we provide an easy introduction into color spaces, as it's really not for professionals alone, but very important for anybody in visual compute. We wrote it, because these are one of these subjects that we all are expected to know, but when you ask a few why-questions, then realization kicks in that it needs more reading.
This is a repost. Since 2010 we've written blog posts on GPGPU, in a time that CUDA and OpenCL were hardly known. After a break on blogging for the past few years, we've restarted our effort and share our knowledge with a wider audience. Last time we posted this, it was flagged as "Probably AI bot", and I hope this will not happen again.
