Atmos vs qualpal
Both stand on color palette generators. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan ExtensionWeb
Atmos combines palette-making tools, contrast checks, sharing, and broad export options for UI design work. Note the one-project free-plan limit and the SVG-only exports during the trial.

Qualpal focuses on perceptual distinction, with options for background-aware generation, palette extension, and color-vision simulation. Its approach does not evaluate visual harmony, so that consideration must be handled separately.
