# Color Engine

> Use this tool when you need to efficiently process and manipulate colors in your application, solving problems such as color conversion, contrast ratio calculation, and color ramp generation. The Color Engine takes in color strings and display profiles as input and outputs parsed colors, contrast ratios, and perceptual color ramps. It is ideal for use cases requiring fast, in-memory color processing, such as web development, design, and accessibility testing.
