Add an "Affect Color" checkbox for the brush in Vertex Paint mode.

Currently, there is an "Affect Alpha" checkbox. However, an additional mode is needed to allow working only with the alpha channel—not just painting, but also blurring and using other editing tools on the alpha channel without affecting the color.

could (should) be 3 separate fields R, G, B - because some of us at gamedev paint on R,G,B as they were separate layers of data.

we use the color palette addon for painting with rgb, but it painting in one attribut channel. and use the hotkeys. 1 for black color, 2 for red, 3 for green and 4 for blue

TBH Due to vertex paint mode deficiencies, i tend to utilize geometry nodes and weight painting when i paint separate data with VertColors.
