RGB numeric values have no meaning without a color space to interpret them

The same triplet of R, G, B numbers can produce visibly different colors on screen depending on which color space is used to interpret them. A color space assigns meaning to numeric values: it specifies how each number maps to actual light intensity and which physical colors the primaries correspond to. Two pickers both reading 255,128,0 may show completely different oranges — both correct, just in different spaces. For generative visuals: specifying vec3(1.0, 0.5, 0.0) in a shader is only meaningful once the target color space is established. The common misconception is that RGB values are ‘objective’ — they are not.

Examples

Two RGB color pickers with identical slider positions produce different colors; only pure black (0,0,0) looks the same in both because no color space can reinterpret zero intensity.

Assessment

Given two screenshots rendered from the same RGB values but in different color spaces, explain why they differ; then state what additional information uniquely specifies a color.
