What it does
Cool Backgrounds collects abstract background generators and downloadable images. Its options include triangles, particles, gradients and layered topography, with colour-specific galleries and solid shades.
Browse by a colour family when the design already has a direction. The blue page, for example, brings solid fills, triangle patterns, topography, particles and gradients into one gallery. Hover an image and use its download button for the full-resolution version.
The shade list provides another route: select a named shade to copy its HEX code or download a plain background. The page’s prepared gradients can be copied as CSS or downloaded as images. This gives a web layout a choice between a stylesheet background and an image file.
The main collection also includes credited Unsplash photographs alongside generated abstract work. Keep that distinction when choosing an asset and checking its applicable use terms. The linked CSS Gradient editor is a separate tool for making a custom gradient.
