Colorpicker rounding errors
Right now the color picker always turns convert the color first to HSB
before setting the other values.
When I try to get the color: #336699 or RBG 51,102,153 it always gets
rounded to #326699 (50,102,153)
And it happens to other colors too !
HSB is nice, but it's always a color approximation. Please change it
to RGB or HEX
