Building Color Models and Exploring Color Spaces in Three Dimensions with Blender

This is a brief excerpt from NoFilmSchool

Color spaces and color models can be difficult to wrap your head around completely. There are additive and subtractive spaces, like RGB vs. CMYK, and different format/display technologies, like analog’s YUV vs. digital’s YCbCr — all of which you may have to traverse to achieve the final ‘look’ you want for your imagery. Not to mention that many color spaces are not absolute, meaning they don’t profile device-specific color representation. This can certainly induce a bit of a headache for newcomers to the color science realm. A great post by photographer Mark Meyer, featured recently on PetaPixel, explains how you can quite literally better-orient yourself to color spaces and models by, well, modeling them — in 3D open suite Blender, no less.

Now, many of us may not think of color spaces three-dimensionally, but a 3D perspective on color is, in a way, already dictated by the very terminology in use here: color space (not “color shape” like a rectangle) and color model (not “color map”) would seem to imply a dimensionality beyond the flat charts filmmakers may be used to grading with in our NLEs. Mark Meyer (originally on his own site, and featured by PetaPixel) takes …
