solidcolor

A solid color is a color applied to a surface that is uniform across the area, without gradients, shading, textures, or patterns. In graphic design, digital imaging, and printing, it provides a single, unvarying hue.

In digital contexts, solid colors are encoded in color spaces such as RGB (for displays) or hex codes like #RRGGBB. Alternative representations include HSL/HSV. In print, solid colors are specified in CMYK. Color management systems use profiles to reproduce a given color consistently across devices.

Solid colors are widely used for user interface elements, logos, backgrounds, textiles, and paintings. They offer simplicity, strong branding, legibility, and fast rendering. When contrast is needed, they are often paired with complementary or contrasting colors, or used against patterns to create visual interest.

Limitations include variations in appearance due to device gamut, lighting, and calibration. Some colors cannot be reproduced exactly on all media, requiring color conversions or dithering. In flexible designs, too many solid colors can create a flat or monotonous look.

In web and vector graphics, solid color is a basic fill operation, typically set via properties such as background-color or fill, using values like red, #FF0000, or rgb(255,0,0).
