Not a medical or clinical tool

The Color Blindness Simulator is a visualization aid built on a standard published sRGB→LMS approximation. It is not a diagnostic tool and cannot substitute for an actual color vision test. Severity of color vision deficiency varies significantly between individuals, and the simulation shows one representative approximation, not a personalized result. If you suspect you or a family member has a color vision deficiency, consult an optometrist or ophthalmologist.

Not a print-production tool

The CMYK values shown in the Color Converter use a standard, unmanaged RGB→CMYK formula. They do not account for your specific printer, ink set, paper stock, or ICC color profile. Always confirm colors with your print vendor's proofing process before a production run.
