Frequently asked questions

How do I convert HEX to RGB?

Split the six hex digits into three pairs and read each pair as a base-16 number. For #6366f1, 63 is 99, 66 is 102 and f1 is 241, so the color is rgb(99, 102, 241). Type the HEX into the tool and RGB and HSL update instantly.

How do I convert RGB to HEX?

Convert each of the red, green and blue values (0 to 255) to two hex digits and join them with a leading #. For example rgb(255, 0, 0) becomes #ff0000 and rgb(0, 128, 255) becomes #0080ff. The tool does this as you move the RGB inputs.

What is the difference between RGB and HSL?

RGB mixes red, green and blue light amounts, while HSL describes a color as hue (0 to 360 degrees on the color wheel), saturation and lightness in percent. HSL is easier to adjust by hand, for example to make a shade lighter you only change L.

What color formats does the tool support?

It converts between HEX, RGB and HSL, and each value can be copied. HEX must be a full six-digit value such as #6366f1 to be applied, so shorthand forms like #fff need to be expanded to #ffffff first. It does not include an alpha (transparency) channel.

How do I get a lighter or darker shade of a color?

Change the lightness value in HSL while keeping hue and saturation the same. Raising L toward 100 percent gives lighter tints, lowering it toward 0 gives darker shades. Changing HEX or RGB values directly is much less predictable.

Why does my HEX color not update?

The tool only applies a HEX value that matches # followed by exactly six hex digits, meaning 0 to 9 and a to f. Three-digit shorthand, missing # inside an incomplete entry, or letters beyond f are ignored until the value is valid.

Is my data shared when using the Color Picker & Converter?

No. Toolskyt operates under a zero-server policy. All calculations, data formatting, and file exports are executed locally on your machine.

Do I need to sign up or pay to use the Color Picker & Converter?
