Frequently Asked Questions
Is my data sent to a server when using the Color Blindness Simulator?
No. The Color Blindness Simulator is a fully client-side utility. All data processing, calculations, and conversions are handled locally in your browser. No input text, payloads, or keys are uploaded to any external server.
Which color formats are supported?
The converter supports HEX, RGB (Red, Green, Blue), HSL (Hue, Saturation, Lightness), and CMYK (Cyan, Magenta, Yellow, Black) formats.
Does it support color alpha transparency (opacity)?
Yes, you can adjust color opacity by converting to RGBA, HSLA, or 8-character HEX formats that define the alpha transparency channel.
What is WCAG contrast validation?
It measures the luminance contrast ratio between background and foreground colors. A ratio of 4.5:1 is required for normal text under WCAG AA standards, and 7:1 for AAA standards.
