Color Mix Tool

Color Mix Tool is a domain-focused utility that computes a blended color from multiple inputs. It accepts hex codes or rgb(a) values for 2–5 base colors and returns a precise resulting color in hex and RGB formats. The core purpose is to support palette creation, brand color alignment, and accessibility testing by providing deterministic color output based on user-specified weights or a simple averaging method. The tool is designed for designers, front-end developers, and brand managers who need rapid color decisions without manual calculations.
Core operation uses straightforward blending rules. Users supply 2–5 colors; the tool converts inputs to linear RGB, applies either an average (equal weights) or weighted blend, and then converts back to sRGB hex and RGB values. Advanced options can include sequential blending of colors, alpha-aware blends, and weight adjustment to emphasize dominant colors. The outputs include hex, RGB, and a perceptual luminance estimate to help with contrast planning. This enables quick checks against accessibility guidelines (e.g., WCAG) and consistency across UI components.
Outputs can be copied into design systems or code bases, or exported into pipelines for asset generation. The tool handles common input formats, validates color strings, and returns clear error signals for invalid inputs. It does not fetch external data or perform gradient generation; it focuses strictly on deterministic color mixing and straightforward color format conversions.
