How to get this effect

Short version: make the text into a selection, switch to the yellow-box layer and clear that selection. @Member#334542 mentioned Photoshop, but the same idea is trivial in GIMP; @vishalkhialani noted they solved it — below are a compact destructive workflow and a recommended non‑destructive layer‑mask workflow, plus quick fixes for common problems.

• Destructive (fast)

  • Open the background as a layer.
  • Create a new layer above it and fill it with your yellow color (Bucket Fill).
  • Use the Text tool to create your text on its own layer.
  • Right‑click the text layer -> "Alpha to Selection" (or Layer > Transparency > Alpha to Selection).
  • Select the yellow layer in the Layers dialog. If Delete does nothing, right‑click the yellow layer -> "Add Alpha Channel".
  • Press Delete (Edit > Clear) to cut the text-shaped holes in the yellow layer.
  • Turn off or remove the text layer and deselect.

• Non‑destructive (recommended)

  • Create the text and make the selection as above.
  • Invert the selection (Select > Invert).
  • With the yellow layer active: Layer > Mask > Add Layer Mask -> Initialize to "Selection" -> Add.
  • Hide the text layer. Edit the mask (paint in black/white) to refine the cutout later.

Troubleshooting/tips: enable antialiasing in the Text tool for smooth edges; if you see a faint yellow halo, try Select > Shrink (1 px) before deleting or fine‑tune the layer mask with a 1 px Gaussian blur on the mask. Save an .xcf to keep layers; export as PNG to keep transparency or export a flattened JPG if the background is meant to be baked into the image.
