Check GIMP Foreground and Background Colors Before a Mask Gradient
By ImgHeal · Updated
A mask gradient depends on the chosen gradient and its endpoint colors. Check those settings before drawing a transition across a repair. An inverted or colored endpoint can produce unexpected coverage even when the drag direction looks right.

State which side should remain visible
Choose the two regions the mask should blend and write down which side should reveal the repair. Inspect the mask separately from the image layer so you know where the operation will land. Preserve the existing mask in the working project before testing. A gradient is suitable for a broad transition, but it is not a substitute for a precise boundary around lettering, a face, or another small object.
Inspect gradient and color endpoints
GIMP's Gradient tool documentation explains resource selection and foreground/background-dependent gradients. Read the active gradient name and the current foreground and background colors. For a visibility mask, understand how its light and dark values affect coverage rather than relying on the visual color swatches alone. Make a short test on a duplicate mask and inspect its actual grayscale transition. Check endpoint reversal and repeat behavior separately from the drag direction.
Review the blended repair
Apply the intended transition and inspect the mask as well as the composite. Check for a visible tonal seam, an overwide fade, or unintentionally weakened repair coverage. Compare the source at the transition's beginning and end. Save the accepted editable mask and a separate output file. If the repair crosses several different materials, use additional local refinement instead of forcing one gradient across all of them. A smooth fade can conceal a mismatch without making the reconstructed content historically reliable.

Questions about this restoration task
Does reversing the drag always fix an unexpected mask gradient?
Not necessarily. The active gradient, endpoint reversal, colors, and mask target also matter. Test those states deliberately.
