Utilities for three-dimensional models: mesh simplification and preparing a model for animation, right in the browser with no heavy editor to install.
Convert color between HEX, RGB, RGBA, HSL and CMYK, pick palettes, check contrast and extract colors from an uploaded image.
HEX, RGB, HSL and CMYK color converters, palette building, contrast checking and image color extraction, plus utilities for 3D models.
This section covers the work that happens between a mockup and the markup: converting a color from one notation to another, building a palette, checking whether text stays readable on its background, pulling the dominant colors out of an existing picture. The color converters cover every common pair, including CMYK for print. A separate subcategory holds utilities for three-dimensional models. Nothing here needs an account, and everything runs in the browser, so it suits both a one-off value check and steady work on a layout.
