Sorry about a mistake. ColorData[_, "Images"] should read ColorData[_,
"Image"]. Also, ColorData[_, "Panel"] will bring an interactive tool,
which will return RGB values directly by clicking swatches.

Also, the color names should be given as a string.

You can find more about the ColorData via our documentation:
