Available comparators are:
- `CmpRGBComponents` - simple RGB components difference: `abs(r1-r2)+abs(g1-g2)+abs(b1-b2)` (default);
- `CmpEuclidean` - [Euclidean difference](https://en.wikipedia.org/wiki/Color_difference#Euclidean);
- `CmpCIE76` - difference of two colors defined in [CIE76 standart](https://en.wikipedia.org/wiki/Color_difference#CIE76).
