ColorGenerator

ColorGenerator is a compact Resolve FX Generate effect that makes a single chosen color. Unlike Fusion Background, the captured Inspector does not show canvas size, gradient geometry or an Alpha field. These two different tools should not be described as interchangeable.

The original ColorGenerator1 screenshot shows Controls and a collapsed Settings tab. Controls contains a Color swatch, an eyedropper, Red/Green/Blue sliders at 1.0 and diamond-shaped keyframe controls. The swatch is white because all three components equal one.

Blackmagic describes Color Generator under Resolve FX Generate as creating one color with a color picker or eyedropper. It can produce a fill, a color wash or a branch to mix downstream, but its own Controls are not a substitute for compositing or spatial masks.

The eyedropper samples the image ENTERING the current node, not the already generated color. If the source has been converted through a CST, LUT or correction, the sampled value comes from the upstream state after those operations.

RGB exposes three independent numerical components for the chosen color. The saved screenshot shows each at 1.0. In nominal RGB terms 1/1/1 is white, 0/0/0 black and 1/0/0 red; perceived appearance still depends on working space and display transforms.

Do not confuse the Color swatch with opacity: there is no dedicated Alpha slider in the captured Controls. Separate Merge, mask and generator tools determine how the color appears spatially, unless a real installed build reveals more options on a different tab.

The diamonds beside Color and RGB are for parameter keyframes. For a controlled animated tint start with just two keys on one or two RGB channels, check the Spline interpolation and review the frames between the keys.

For a self-contained color canvas with size, depth and Alpha, use the native Fusion Background node. Its canvas and gradient controls are not automatically ColorGenerator features merely because both tools can result in a colored image.

For a color wash, branch the incoming image: keep the original on Merge.Background and send the ColorGenerator branch to Merge.Foreground. Use Merge.Blend to control overlay intensity while leaving the underlying color definition independent.

For a local color fill, connect Rectangle.Mask or Polygon.Mask to Merge.EffectMask rather than assuming a ColorGenerator-specific mask socket. The design separates what color to draw, where to show it and how strongly to blend it.

For title work route Text+.Output into Merge.Foreground with the color branch on Merge.Background. A narrow title bar is usually better built with a dedicated Background plus Rectangle, rather than covering the whole canvas with opaque color.

Inspect the ColorGenerator output in both RGB and Alpha modes. An RGB image is not a typed mask stream; use Bitmap if luminance or channel data must become a mask. Compare results over dark and light backgrounds for edge artifacts.

If the Viewer looks different from numeric RGB or a brand HEX value, examine the Fusion Viewer LUT, working gamma, CST and final Output Transform before compensating by randomly changing individual color components.

The diagrams here use an editorial image Input, since the Resolve FX manual refers to an incoming signal for the eyedropper. However, the available screenshot shows the Inspector rather than Flow sockets. Confirm exact connectors in a real Resolve 21 build.

For QA, compare before and after, inspect the incoming image and the result, reveal Alpha, review keyframes and verify the roles of Merge.Background, Merge.Foreground and Merge.EffectMask.

The four practice examples are structurally type-checked editorial graphs. They are not importable .comp/.setting compositions and do not establish native rendering or pixel-level behavior of ColorGenerator.
