How to use Create an Image with One Color
- 1. Pick a color. Open the Color swatch and choose or type any hex value, like #ef4444 for red. This is the only pixel value the whole output image will contain.
- 2. Set Width and Height. Enter the pixel dimensions you need, such as 640 by 480 for a standard placeholder or 1920 by 1080 for a full banner. Larger values just produce a bigger flat file.
- 3. Generate and download. Click generate to build the PNG in your browser, then download it. Every pixel is identical, so the file compresses to almost nothing regardless of size.
When to use Create an Image with One Color
Create an Image with One Color builds a flat, single-hue PNG at whatever size you specify. It exists for the moments you need a plain rectangle of a specific color rather than a photo or illustration, and typing that color as a hex code is faster than opening a design tool.
- Placeholder backgrounds during layout work. You are wiring up a webpage grid and need a temporary background image behind each card before the real photography arrives. A solid swatch at the right dimensions holds the layout together.
- Brand color reference swatches. A design system lists a primary color as #1e40af and you want a quick visual file to drop into a Slack message or a Figma comment so a teammate can see it without opening a picker.
- Video editing filler clips. A slideshow or video timeline needs a plain colored frame between two clips as a transition backdrop. Generating it here is quicker than creating a new layer in editing software.
- Testing image pipelines. You are debugging an upload or resize pipeline and want a predictable, uncompressed input whose exact pixel value you already know, so any discoloration after processing is obvious.

It belongs to the Image Tools collection on EditSafely, a set of 200 small, focused Image utilities that share the same instant, private workspace.
You can shape the output with 3 settings, including Color, Width (px) and Height (px), and the result refreshes the moment you change one.
