Is there some kind of color chart that I can use to reference when entering different values into the RGB inputs in the color palette?

How do you know what values to enter to make a color? Is this just a matter of dragging the sliders?

Or using the color picker....

It helps if you understand a bit about RGB theory (although Chris is right in suggesting that with the color picker it couldn't be easier).

With RGB the higher the value, the lighter the image. Anything with three values over 240 will always be a pastel color, and over about 250 you are getting to off whites.

If only one value is high, then you will get that color. 255/0/0 is pure red. If you lower the value it gets darker 128/0/0 is a dark red, and when you approach 0/0/0 it gets near black.

To make a lighter red (pink) increase the other two values. So 255/128/128 is a pink. The higher the other two values, the closer you are to white, and the lighter the pink.

There are complementary colors CMY (no K here). To get Yellow, you want the reverse of Blue. Blue is 0/0/255, so Yellow is 255/255/0. The other complements are Cyan and Magenta.

AS you say, playing with the sliders can be informational, but these basics will help.
