singlefilled

Singlefilled is a neologism used in design and digital graphics to describe a fill style where the interior of a shape or object consists of a single, uniform color or tone. The term is informal and varies by context, but it generally contrasts with fills that incorporate gradients, textures, transparency, or multiple layers.

In vector graphics and illustration, a singlefilled shape is produced by a single fill operation that assigns one color value to the entire region. There are no color stops, patterns, or shading within the shape. This approach is common in flat design and in iconography where consistency and clarity are prioritized. Some file formats, such as SVG or AI, support singlefilled shapes as a basic primitive; anti-aliasing can affect the perceived edge softness.

In 3D modeling and rendering, singlefilled can describe materials or shading that render faces with a single diffuse color, without reflections, specular highlights, or texture maps. This is akin to flat shading or cartoon shading, and it is used for stylized visuals, technical illustrations, or performance-sensitive scenes where lighting calculations are minimized.

Etymology and usage notes: singlefilled combines the words single and filled, signaling one fill operation or one color fill. The term is not standardized and may be used alongside related concepts such as solid fill, flat color, or pattern fill. See also solid color, flat design, gradient fill, texture.
