Change grid line color, opacity, and width over a photo. Compare colored guides on a square 6×6 canvas and save the combined PNG.
Blank Square 1:1 grid, 6 rows x 6 columns
A 4×4 drawing grid keeps the portrait in proportion.
Select an image with the colors and lighting you expect to use. A square six-by-six guide appears over it.
Use the preset swatches or custom color picker. Check both highlights and shadows before adjusting opacity and width.
Download the PNG when the lines remain readable without covering important details in the photograph.
No. The selected color applies to the grid as a whole. Individual line colors and per-cell fills are not supported.
Yes. Use Custom line color to select another color, then adjust its opacity with the separate control.
A coral line may stand out against a cool blue scene and disappear into an orange subject. Black works well on light areas but can be difficult to see across deep shadows.
Inspect several parts of the reference rather than choosing a color from an empty canvas. If no single color works everywhere, try a stronger opacity or a slightly wider line and check again.
This tool applies one chosen color to the grid. It does not fill individual cells, create a multicolored spreadsheet, or recolor the objects in your photograph.
Use opacity to reduce how strongly guides compete with the source. A color that looks subtle on a bright screen may be too faint on paper, so a test print is useful for a physical reference.
