Why is base colour wheel only giving me black as an option I don't know when this happened but my base colour wheel doesn't want to cooperate to give me the colours that i want. The problem:

How do i get the colour wheel to show all the colours again and what did i do to make this happen? Thanks!
ps: Not sure if this is related but the animation i have for the + signs are changing alpha value from 0 to 1, using alpha blend as shown:
You have set the luminosity to a low level. Bring it up.

The circle is to set hue and saturation. The strip to the right is to set luminosity.
Alternatively use the sliders for the different color channels.

Or use the Mouse Wheel to adjust luminosity.
