Solid Color Layer design

[don570]

When I create a layer I normally choose Solid color with an image mask. However when I choose 'Solid Color' I noticed the following --->

If a choose Roughness channel and then try to paint I get a confusing warning about needing a texture (see image) A texture can be an image,but it requires an expert to know that. So I would like a better warning message.

Second point-

I understand why it is important to allow a color channel with no associated image i.e. less memory consumed.

I would suggest allowing a layer that is solely a 'Solid Color' channel. Setting up a Roughness channel could be done but would be easier by selecting 'Solid Color with an image mask' The dialog box can provide the instructions to add more channels

The current way that Ucupaint has set up multiple channels works but it is confusing for a newbie. Here is how I would design a Solid Color Layer dialog... There would be only 3 things to choose --> name , Layer channel blending , and color Maybe a fourth option - the level of opacity Ucupaint's override feature would allow the overall roughness to be adjusted.
