Common Use Cases
Web Design & CSS
Convert HEX colors to RGB or HSL for CSS properties like rgba() and hsla() that support transparency. ToolsMio makes switching between formats instant.
Brand Guideline Compliance
Ensure your brand colors are consistent across platforms by converting between HEX, RGB, and CMYK formats used by different design and print tools.
Accessibility & Contrast Checking
Convert colors to HSL to better analyze lightness and saturation for WCAG contrast compliance. Pair with contrast ratio tools for accessible designs.
Cross-Platform Design Handoff
Developers and designers often use different color formats. Quickly convert between formats to bridge the gap between Figma HEX values and code RGB values.
What Should You Know About Color Conversion?
- ✓ HEX and RGB represent the same color in different notations — HEX is shorthand for RGB values in hexadecimal. ToolsMio converts between them losslessly.
- ✓ HSL (Hue, Saturation, Lightness) is often more intuitive for adjusting colors because each channel maps to a human-perceptible attribute.
- ✓ CMYK is primarily used for print. Colors may look different on screen vs. print due to different color gamuts between RGB and CMYK spaces.
- ✓ Always check contrast ratios when choosing text colors on backgrounds. WCAG 2.1 requires at least 4.5:1 for normal text and 3:1 for large text.
- ✓ When using rgba() in CSS, the alpha value ranges from 0 (fully transparent) to 1 (fully opaque), giving you fine control over element transparency.
