Brand Color Distance
Compare two colors and see how far apart they are numerically.
How far apart are two colors?
“Are these two blues actually different?” is surprisingly hard to answer by eye. This tool compares two colors and returns a numeric distance between them, so you can tell whether a brand color drifted, whether two swatches are effectively identical, or whether a pair has enough separation.
A measured distance is more reliable than a glance, especially for near-matches where monitors and lighting fool the eye. Use it to audit brand consistency, catch accidental duplicates in a palette, or confirm two states are visually distinct.
Reading the distance
A small number means the two colors are near-indistinguishable, while a large one means they read as clearly different. The comparison runs locally, so brand colors stay private.
Frequently asked questions
What does the brand color distance checker do?
It compares two hex colors with RGB distance and a plain-English similarity label.
How is color distance measured?
As straight-line (Euclidean) distance between the two colors' RGB values. The maximum, from black to white, is about 441.7.
What do the similarity labels mean?
Under 10 is "Very close" (usually indistinguishable), under 35 is "Close", under 90 is "Noticeable", and anything higher is "Far apart".
Is RGB distance the same as perceived difference?
Not exactly. Human vision is more sensitive to some hues than others, so two pairs with the same RGB distance can look differently far apart. For strict brand matching, a Delta E (CIELAB) check is more accurate.
