How to use the Color Picker
- Tap the color swatch to open your browser's color picker, or type a HEX code directly.
- The HEX, RGB, and HSL values update instantly as you pick.
- Copy all three formats at once, or use the Copy button for just what you need.
- Use the Copy or Share buttons to save or send your result.
Tip: Different tools expect different formats — CSS accepts all three (HEX, RGB, HSL), but some design tools or older systems only accept one, so this tool gives you all three at once.
Common mistakes to avoid
- Assuming HEX, RGB, and HSL for the same color are different colors — they're the same color, just written three different ways.
- Manually converting between formats by hand, which is easy to get slightly wrong.
- Forgetting that HSL's first value is a hue in degrees (0-360), not a percentage like the other two HSL values.
How the Color Picker Works
One color, three formats
This tool uses your browser's native color input to let you pick a color visually (or type a HEX code directly), then converts that single color into all three common web formats: HEX (used everywhere in CSS), RGB (red, green, blue values from 0-255), and HSL (hue, saturation, lightness — often easier for humans to reason about when adjusting a color).
When to use this tool
Use it when you need to match a brand color across HEX and RGB, fine-tune a color's lightness using HSL, or quickly convert a color you've picked from a design into code-ready values.
✓ Pros
- Works instantly, right in your browser
- Converts instantly between HEX, RGB, and HSL with no manual math
- No sign-up, no ads blocking the result
✕ Limitations
- It works with solid, opaque colors — it doesn't handle transparency/alpha values (like RGBA or HSLA).
- Color names (like "tomato" or "skyblue") aren't supported as direct input — use a HEX code or the visual picker instead.
- The visual color picker's exact appearance depends on your browser and operating system, since it's a native browser control.
HEX vs. RGB vs. HSL
When to use each format
All three formats describe the exact same color — the difference is just how easy each is to read, write, or adjust for a given task.
Quick guide to each format
- HEX (
#146356): compact and universal — the most common format in CSS and design tools. - RGB (
rgb(20, 99, 86)): each channel from 0-255 — useful when working with code that manipulates individual color channels. - HSL (
hsl(174, 66%, 23%)): hue, saturation, lightness — easiest for humans to adjust, since raising "lightness" reliably makes a color lighter.
Why HSL Is Easier for Adjusting Colors
If you want to make a color lighter or darker in HEX or RGB, you have to recalculate all three channels by hand, which isn't intuitive. In HSL, the same task is a single number: increasing the lightness percentage makes any color lighter while keeping its hue and saturation the same, and decreasing it makes the color darker. For example, TickmarkTools' brand teal is hsl(174, 66%, 23%) — bumping the lightness to 40% gives a lighter version of the exact same hue, without touching the other two values.
Quick Reference: Common Colors

Black | #000000 | rgb(0,0,0) / hsl(0,0%,0%) |
White | #FFFFFF | rgb(255,255,255) / hsl(0,0%,100%) |
Red | #FF0000 | rgb(255,0,0) / hsl(0,100%,50%) |

Accuracy & limitations
This tool converts color formats accurately, but it's worth knowing the scope:
- No transparency. It works with solid colors only — it doesn't produce or accept alpha/transparency values like RGBA or HSLA.
- HEX and native picker input only. Named colors (like "tomato") aren't accepted as text input — use the visual picker or a HEX code.
- Picker appearance varies. The visual color-selection interface is provided by your browser or OS, so its look differs between devices.
Color Picker FAQ
Yes, the Color Picker is completely free with no sign-up required.
No, they're the exact same color written in three different formats — this tool just converts between them instantly.
All three work in modern CSS. HEX is the most compact and common, RGB is useful for programmatic channel control, and HSL is easiest for manually adjusting lightness or saturation.
No, it works with solid, opaque colors only — it doesn't produce RGBA or HSLA values with an alpha channel.
No, named colors aren't supported as direct text input — use the visual color picker or type a HEX code instead.
No. All calculations run entirely in your browser, and nothing you enter is ever sent to a server or stored.
