Read the background material behind the tools so you can choose formats, compare palettes, and move from quick experiments to implementation-ready decisions.
These articles are designed for people who need more than a single tool result. They explain why one format is easier to maintain than another, how to judge extracted colors before using them in a UI, and what to check before saving a value into CSS, a token file, or a design handoff.
Learn the tradeoffs between HEX, RGB, RGBA, and 8-digit HEX. This guide explains when each format is easier to read, when transparency should be encoded directly, and which mistakes tend to happen during design-to-code handoff.
Understand how to turn extracted colors into practical UI decisions. This guide covers how to assign roles to palette colors, where contrast checks fit into the process, and when a palette needs refinement before it becomes part of a system.
Read a guide first if you are still deciding which format or palette direction you actually need. Context saves time before you start copying values.
Use the tool for the fast conversion or extraction step, then come back to the article when you need a more durable implementation choice.
Treat the final step as documentation. The tool helps you move quickly, while the guide helps you store the result in a way your team can understand later.
If you already know what you need, jump directly into the interactive pages and come back to the guide library whenever you need more context.
Tools are good at producing answers, but guides are better at explaining decisions. Static pages make the site easier to understand before JavaScript runs, give search engines more context, and help visitors judge whether a tool fits their workflow.
