About the Solid Color Image Generator

A flat image in a specific colour turns out to be needed surprisingly often: as a background where CSS is not available, as a spacer in an email template, as a colour reference for a printer, or as a placeholder while a real image loads.

Type a colour in any format — HEX, RGB, HSL or a CSS colour name — set the dimensions, and take the file. A batch mode produces one image per colour in a list, which is how a whole brand palette becomes a folder of swatches in one step. Transparent PNGs of any size are available too, which is the other thing this gets used for.

Key features of the Solid Color Image Generator

Any colour format

HEX, rgb(), hsl() and CSS colour names are all accepted, so you paste whatever you already have.

Down to one pixel

A 1 by 1 PNG under 100 bytes, which is the classic trick for a stretched background or a spacer.

Transparent output

Set the opacity to zero for a fully transparent PNG of any size.

Whole palettes at once

Paste a list of colours and each becomes its own file inside a ZIP named after it.

Three formats

PNG for transparency, JPEG for the smallest file, WebP for both at once.
