Blend Color
blend-color
Sets the color of the blend layer. Valid values are RGB, ARGB, RRGGBB, AARRGGBB, or a CSS color name.
blend-color replaces the color given in blend, and it does so even when its own value does not parse as a color. When blend holds an image URL, setting blend-color draws the color instead of the image.
Aliases: blendcolor, blend-clr, blendclr.
Use blend-color[N] to target a specific blend layer, where N is 0–3. Layer 0 is either the bare blend-color or blend-color[0]; if both are supplied, the bare name wins.
