MIXORA CONCEPT
Lightness and value
How light or dark a surface color appears relative to white and black under comparable conditions.
Artists often say value; color science uses more specific lightness measures. Value structure can remain readable even when hue is removed, which is why grayscale checks are useful.
What “Strong evidence” means
The core definition or effect is well established across authoritative standards, foundational research or a broad research literature. The label does not make every practical prediction certain.
VISUAL EXPLANATION · MARKER BOARDA vivid blue and muted brown can have similar value even though their hues are unrelated.
A color that feels dull is not necessarily too dark.
Does the mismatch remain when both target and sample are viewed in grayscale?
The attribute by which a color is described as red, yellow, green, blue or an intermediate family.
→colorChromaThe colorfulness of an area judged relative to a similarly illuminated white or gray reference.
→color × thought × bridgeSimultaneous contrastA color can appear different when its surrounding colors change, even when the stimulus itself stays the same.
