Colors
← Back to All Tags
Colors is where I want to treat color as more than a label on a spectrum. It is the tag for posts about how materials, structure, illumination, and visual interpretation combine to produce what we finally see.
That bridge matters because measured spectra and perceived color are related, but they are not identical. This is where I want to keep both sides in view: the physical origin of color and the design choices that shape its appearance in practice.
A good place to start:
