NOTE: Before you is the "Makarov's Foursquare", it reflects only the pure colors
(without canceling each other out), plus the scale of shades of gray (lower left
corner);
if you found your desired color of the table - use provided in the appropriate cell
color code;
if the color is "somewhere between ...", then interpolating between the codes of
neighboring cells determine the correct code;
if you could not read the code in the box - "daub" in the cell by the mouse while
pressing the left button - the code will be displayed.
