Advanced vertex color painting tools for Blender 4.2 and 5.0. The add-on adds a dedicated 3D View sidebar panel for filling, previewing, blending, adjusting, baking, and generating vertex color data on mesh color attributes.

Features:

Channel Preview: Preview RGB or isolate R, G, B, and A channels as grayscale directly in the viewport.

Global Channel Control: Choose the target color attribute and limit operations to selected RGBA channels.

Blend Modes: Apply tools using Normal, Add, Multiply, or Overlay blending.

Color Fill: Store five quick colors and apply them to the selected mesh data.

Random Fill: Generate randomized vertex colors for selected channels.

HSV Adjustments: Shift hue, saturation, and value with live preview, then apply or reset the result.

Linear Gradients: Create simple local/world gradients, auto-guessed gradients, pencil-based gradients, or curve-path gradients.

Radial Gradients: Draw radial vertex color gradients directly from the viewport.

UV Gradients: Use U or V coordinates from a selected UV map as vertex color gradient values.

Image and AO Baking: Bake image colors or ambient occlusion data into vertex colors.
