Frequently Asked Questions

Everything you need to know about our advanced color converter.

How do I convert HEX to HSL?
Simply paste your HEX code into the main input. The tool instantly calculates the Hue, Saturation, and Lightness (HSL) values, which you can copy from the conversion grid.
What is the difference between LAB and RGB?
RGB is based on how screens display light, while LAB is a perceptual color space designed to match human vision. LAB is often better for creating consistent color intervals.
Does it support Tailwind CSS v4 themes?
Yes! Click 'Generate CSS' in the Tints section to get a complete @theme block with CSS variables specifically formatted for Tailwind v4.
How are contrast ratios calculated?
We use the standard WCAG 2.1 formula which compares the relative luminance of two colors to ensure readability for users with visual impairments.
What is an Analogous color scheme?
Analogous colors are groups of three colors that are next to each other on the color wheel. They are often found in nature and create pleasing, serene designs.
Can I generate a 50-900 color scale?
Yes. Our 'Tints' generator uses professional mixing to create a balanced scale from your base color, perfect for building UI design systems.
How do I get a complementary color?
The tool automatically calculates the color exactly 180 degrees opposite your base color on the wheel, displayed in the 'Color Palettes' section.
Does it support CMYK for print design?
Yes, we provide CMYK conversions using industry-standard mapping to help you transition your web colors to print-ready assets.
What is the HSL mapping graph for?
It allows you to visualize where your color sits in terms of saturation and lightness, making it easier to pick consistent accent colors.
Can I copy colors in Bootstrap format?
Absolutely. We provide snippets for standard Bootstrap utility classes like 'text-primary' or 'bg-danger' based on your color's closest match.
