Does not support all color space (high saturation and high lightness)

[FlorentMasson]

While using this color picker, I realized it is placing the dragger at the wrong place for colors with high saturation and lightness

Here is what the same color looks like in chrome devtools

Also, there's no way noselect a color with high saturation and lightness on the spectrum.
There's a mismatch between the visually selected color and the actual color returned

On the screenshot above, the visually selected color is #DFABAA while the returned color is #e9dcdc
