Frequently Asked Questions
What color formats are supported?
We support HEX, RGB, HSL, HSV, HWB, LAB, LCH, OKLab, OKLCH, Display P3, Rec. 2020, ProPhoto RGB, Adobe RGB (1998), and XYZ color spaces with both D65 and D50 illuminants.
How accurate are the color conversions?
Our conversions use the industry-standard Color.js library, ensuring high accuracy across all color spaces. Wide gamut colors are properly handled with appropriate color space transformations.
Can I convert colors outside the sRGB gamut?
Yes! We support wide gamut color spaces like Display P3, Rec. 2020, and ProPhoto RGB. These can represent colors that standard sRGB monitors cannot display.
What's the difference between LAB and OKLab?
LAB is the traditional perceptually uniform color space, while OKLab is a newer, improved version that better matches human color perception. OKLab provides more intuitive results for color manipulation.
