hm the rect actually isnt quite as easy as ive put it there (even tho its close enough to get the general idea)
the actual algorithm doesn seem to use whole numbers, hence my explanaition has some mistakes (the big box values are correct tho)

this lil thing should allow you to pick any rect color:

bumpedit: mouse hold working, and you can also drag the cross outside the window to pick any color on your screen - it will display the picked hex color on the left and the closest rect on the right
