So I'm having this issue with an applied color not looking the same as the color i made in the color picker.
I go to the color picker and make a 100% cyan color and then use the paint bucket and apply to blank layer.
Once applied it is visibly different from the color in the color swatch thumbnail, and when i pick the color i just made in the layer with the
eyedropper tool into the 2nd color slot you can see that they are not the same color. Different values and everything!
