In what format is it more accurate to compare two colors for similarity?

Question

Working with color

Task: there is a color in RGB or HEX, you can always convert it to another.
You need to compare it with a set of colors and show which color it is closer to. How to do it more precisely?
Through HSV or RGB difference comparison?

Answer 1

if you just need to compare color number 1 and color number 2 and get true or false as a result, then it doesn’t matter, but if you need to calculate the nearest color, it’s much more convenient using HSV.

Answer 2

Depends on similarity criteria. But it is better to compare by HSV, with different weights of HS and V (then, for example, V can be taken into account the least, and light red will be more similar to dark red than light red to light orange)
