You can use the photoshop color picker tool to select the tool.

thank you

What version of Houdini are you using? My recommendation would be to put a box, uv map it, then subdivide and scale it up so you have a nice sky dome. Slap a constant material on it and use whatever color map you want. Be sure to go to the light linker and disable it from casting shadows.
