Why do some colors look different on different screens?

Screen color accuracy depends on the display panel type, calibration, brightness settings, and color profile. Design for the sRGB color space for maximum cross-device consistency.

How do I pick colors that work for colorblind users?

Avoid relying on color alone to convey information. Pair color with text labels, icons, or patterns. Ensure palette colors remain distinguishable under common color vision deficiencies using simulation tools.

Can I use this picker to match a color from an existing image?

This picker does not include an eyedropper for images. Use a browser extension like ColorZilla or your OS color picker to sample from images, then enter the value here for format conversion.

What is the best color format for CSS custom properties?

HSL is the most practical because you can adjust lightness or saturation dynamically. Store the base hue and saturation, then derive variants in CSS. Modern CSS also supports oklch() for perceptually uniform manipulation.

How many colors should a website have?

A typical system uses 1-2 primary colors, 1-2 secondary colors, 3-5 neutrals, and 3-4 semantic colors. Each with a tint/shade scale gives 30-60 total values derived from 6-10 base colors.

What is the difference between RGB and CMYK?

RGB is additive (light-based) for screens. CMYK is subtractive (ink-based) for print. Web browsers only use RGB-based models. Converting between them will not match perfectly due to different color gamuts.

Does color choice affect SEO?

Not directly. Indirectly, poor color choices increase bounce rates and reduce time on page, which can affect behavioral ranking signals. Accessible color choices improve user experience metrics.

CSS Color Picker

Pick colors from a visual palette, convert between hex, RGB, and HSL formats, and grab the exact color codes you need for web design and branding work.

This is a utility tool for quick color reference. It does not analyze your site's color scheme or accessibility.

CSS Color

Colors in web design live in three formats, and if you have ever Googled "hex to rgb" at 2 AM, this tool is about to become your new best friend. HEX codes are the ones CSS developers have memorized since the 90s. RGB values describe light mixing. HSL values describe color the way humans actually think about it. Pick a color visually and get all three formats instantly — no mental math, no converter tab, no excuses.

Understanding Color Formats

HEX is the most common format in web development. It is a six-character string like #2bb5a8 that represents red, green, and blue channels in hexadecimal. It is compact, widely supported, and what most developers default to in stylesheets. The downside is that it is not human-readable — you cannot look at #2bb5a8 and intuit the color without experience.

RGB describes a color as three numbers between 0 and 255, one for each light channel. rgb(43, 181, 168) means low red, high green, moderate blue — which produces a teal. RGB is intuitive for people who think in terms of light mixing and is the native format for screens. CSS supports it directly, and JavaScript canvas operations use it extensively.

HSL stands for hue, saturation, lightness. It describes color the way a designer thinks: hue is the position on the color wheel (0-360 degrees), saturation is how vivid the color is (0-100%), and lightness is how bright or dark (0-100%). HSL makes it easy to create color variations — darken by dropping lightness, desaturate by dropping saturation, shift the shade by rotating the hue. It is the most practical format for design work, and once you start thinking in HSL, you will wonder why you ever typed hex codes by hand like a caveperson.

Frequently asked questions

Which color format should I use in CSS?

All three are valid in modern CSS. HEX is the most common by convention and slightly more compact. RGB is useful when you need an alpha channel (rgba). HSL is ideal when you are building design systems because it is easier to create consistent variations. Pick whichever fits your workflow — browsers handle all of them identically.

What is the difference between HEX and RGB?

They represent the same information in different number systems. HEX uses base-16 (0-9 and A-F), RGB uses base-10 (0-255). #FF0000 and rgb(255, 0, 0) are the exact same red. The conversion is purely mathematical. HEX is shorter to write. RGB is easier to read if you are not fluent in hexadecimal.

Can I add transparency to these values?

Yes. In CSS, use rgba(43, 181, 168, 0.5) for 50% opacity in RGB format, or hsla(174, 62%, 44%, 0.5) in HSL. HEX supports an optional fourth pair of characters for alpha: #2bb5a880 would be roughly 50% transparent. Modern CSS also supports the newer syntax without the "a" suffix: rgb(43 181 168 / 50%).
