Frequently asked questions
Quick answers to common questions.
Are these tools free?
Core color utilities are free to use; premium badges only apply where a tool is explicitly marked Pro.

Deficiency previews are approximations for design review — not clinical diagnostics.
Can I save palettes?
Use the color history manager to normalize lists today; persistent cloud history may arrive in a future release.
