Adjust Vertex Colors dialog

With the Adjust vertex colors dialog you can fine-tune the vertex colors of the selected vertices or faces.

• Adjust HSV (Hue, Saturation, Value): As the names say. Hue values from -180 to 180 degrees, the other from -100 to 100.
• Add base color: Adds or subtracts a base color to or from the selected verts.
  
• Color Balance: As the name says.
• Adjust Brightnes/Contrast: As the names say.
• Smoothen: This smoothens hard vertex color borders in the selected verts.

The calculations are done top-down, which means that first HSV is calculated, then base color, then color balance etc. If you want another sequence, you'll have to use this dialog twice or more.
