Frequently Asked Questions
What is the difference between HEX, RGB, and HSL?
HEX uses hexadecimal notation (#RRGGBB), RGB specifies red, green, blue values (0-255), and HSL uses hue (0-360), saturation (0-100%), lightness (0-100%). HSL is often easier for humans to understand and adjust.
What is HSV and how is it different from HSL?
HSV uses hue, saturation, and value (brightness) instead of lightness. In HSV, increasing value always makes the color brighter. In HSL, increasing lightness past 50% makes the color lighter towards white.
What is CMYK used for?
CMYK (Cyan, Magenta, Yellow, Key/Black) is used in print design. If your project involves printed materials, use CMYK values to ensure colors match between screen and print.
How do I convert RGB to HEX?
Each RGB component (0-255) is converted to two hexadecimal digits. For example, rgb(255, 87, 51) becomes #FF5733. This tool does it automatically.
Why are my HEX colors not displaying correctly?
Make sure your HEX value is 3 or 6 characters after the # symbol. Valid formats: #RGB (3-digit shorthand) or #RRGGBB (6-digit). The tool will show an error for invalid input.
Can I use this tool for CSS colors?
Yes! All formats output valid CSS color values. Copy the HEX, rgb(), or hsl() format directly into your CSS stylesheets.
What does the contrast ratio mean?
The contrast ratio measures the difference in luminance between two colors. WCAG requires at least 4.5:1 for normal text and 3:1 for large text to be accessible.
How do I make a color lighter or darker?
In HSL, increase the lightness (L) value to make lighter, decrease to make darker. In HSV, increase the value (V) to make brighter. The tool lets you adjust these values interactively.
Can I convert a color to Pantone?
No. Pantone (PMS, Pantone Matching System) is a proprietary physical ink system whose color book is not in the public domain, and no mathematical formula can map a screen color to a printed spot ink. So no online converter can give you an official Pantone match: other online tools show nearest approximations from published lookup sets, and only Pantone's licensed software gives closest matches against its ink database. For certified print work, check a physical Pantone fan deck or the official Pantone Color Finder, and expect the printed result to differ from your screen anyway.
Can I save my color palettes?
This tool focuses on conversion. For palette management, use our color picker tool which supports saving and organizing colors.
Can I convert rgba() colors with alpha transparency?
No. This tool converts opaque colors (HEX, RGB, HSL, HSV, CMYK) and does not carry an alpha channel. There is no standard HEX/RGB/CMYK representation for semi-transparent colors, so pasting an rgba() or hsla() value here converts only the RGB/HSL part and ignores the alpha. For designs that need transparency, use rgba()/hsla() directly in CSS or keep the color in a design tool that supports alpha.
Can I pick a color directly from an image?
No. This tool converts color codes you type or choose from the color picker; it cannot read pixels from an image. To grab a color from an image: open it in any photo editor and use the eyedropper tool, or take a screenshot and use the browser devtools color picker (right-click the image, Inspect, then click the color swatch). Paste the HEX or RGB value you get back here to convert it.
The same color looks different on my other tools or devices: is the conversion wrong?
The math is exact: a given HEX always maps to the same RGB/HSL values here. The differences you see come from color spaces and displays: wide-gamut monitors (P3) render more saturated colors than sRGB, and uncalibrated screens drift. If your design tool shows a different number, check whether it is in sRGB or P3 mode. For print, CMYK conversion is approximate by design, so always proof against a physical fan deck.
This tool's HSL value differs from another website's: who is right?
Both can be right. HSL has two conventions that trip people up: hue is usually 0-360 degrees (this tool follows the CSS standard), but some sites display radians; and HSL vs HSB/HSV are different models where S and L/B mean different things. A difference of 1 unit (like 50% vs 51% lightness) is normal rounding between conversions. Compare the RGB values instead; if those match, the colors are identical.
