What color formats and adjustment controls does Colorpicker support?

Colorpicker lets you choose colors with three RGB sliders and read the result as a hexadecimal or RGB code in real time. HSL and CMYK are not available yet — the site describes them as coming in future releases. So if you need CMYK values for print work today, Colorpicker is not the tool for that step; if you need fast RGB/HEX picking and adjustment on screen, it fits.

Color formats available now

The practical workflow is: adjust with the RGB sliders, then copy the HEX or RGB code that updates as you move them. The site notes you can see the code "without losing your last adjustments," meaning the readout tracks your current slider positions rather than requiring you to confirm first.

Adjustment controls

RGB sliders

The three sliders are the primary way to set a color. Each slider maps to one channel, so you can dial in a value directly or nudge an existing color toward a target.

Tint

Tint is a separate adjustment tool rather than a format. It generates shade levels from a picked color, and the site states these levels are based on HSL (hue, saturation, brightness). Currently there are three levels of shades. Creating your own shade layers is described as a future release.

This is the one place HSL logic already appears in the app — as the basis for generating tints, not as an input format you can type into.

Access to controls

Every feature is reachable from the toolbar and via shortcuts, so you can switch between picking, adjusting, and storing colors without hunting through menus.

Where the formats come from

Two tools feed colors into the interface:

• Picker grabs any color on your screen — from design software, a browser, or an image — and shows it in the Colorpicker interface in real time, so you get the HEX or RGB code immediately.
• Colorsbook stores colors in multiple palettes. Clicking a saved color puts it back into the Colorpicker interface for further adjustment.

So a typical sequence is: Picker to capture a color from anywhere on screen → RGB sliders to adjust it → Tint to build out shades → Colorsbook to save the result.

What this means for your choice

Choose Colorpicker if your work runs on RGB and HEX — web design, UI work, quick on-screen sampling — and you want picking, adjusting, tinting, and palette storage in one desktop app. The site describes it as free and open source, with a downloadable app and an online version.

Hold off if you need CMYK output for print, or if you want to enter HSL values directly. Those formats are announced as future additions, not current features, and the site gives no release date. For those cases you would need a second tool alongside Colorpicker rather than instead of it.
