When you manually drag the knob in the color picker to the bottom row of the color box (including botton corners) you do not get the correct value. Instead all channel cap out at 252 instead of 255. So if you try to pick white fore example you will get the values (252,252,252) in RGB mode or #FCFCFC
Numeric inputs work correctly.
Steps to reproduce: Open any project, manually try to edit one of the palette colors by double-cklicking, and try to select any color from the bottom edge of the color rectangle.
