ONELESS / COLOR
A useful color starts with a place to explore. Move through a custom color field, narrow the hue, and compare your current shade with the original. Color Picker keeps the visual choice beside the values you can paste into a stylesheet or design brief.
Open Color Picker. JavaScript powers the workspace; the full guide is available below.
UNDERSTAND THE RESULT
Hue chooses the color family. Moving right in the field adds saturation; moving upward increases brightness. Brightness here belongs to the HSV control, while the HSL output describes lightness. They are different measurements.
100% is opaque and 0% is transparent. Below 100%, HEX includes a final alpha byte and RGB/HSL include an alpha channel. The checkerboard is a viewing aid, not part of the copied color.
Original remains the starting violet while Current follows your changes. Reset restores that shade and full opacity. This makes small adjustments easier to judge without relying on memory.
HOW TO USE IT
A WORKED EXAMPLE
Enter #336699, then set Opacity to 50%. The HEX output becomes #33669980. The final 80 is the nearest 8-bit representation of half opacity; it is not another blue channel.
EVERYDAY USES
Start from a known HEX and adjust its saturation or brightness while keeping the original beside it. Check the final text/background pair with Color Contrast Checker before using it for readable UI.
Copy the format that fits your stylesheet. A translucent accent looks different on different backgrounds, so test it in its destination.
LOCAL WORKSPACE
The tool processes color values locally. It does not upload the input to a processing server or save it in browser storage. Leaving or reloading the page clears the working state. Copying places the selected result on your clipboard; sharing sends only the page address without your working values.
These tools describe sRGB colors. Browser decoding, color management and the display can affect what you see; they are not an ICC proofing workflow or a print-color guarantee. Read the site privacy policy for information about the surrounding website.

QUESTIONS, ANSWERED
This picker uses an opaque HEX base and a separate opacity control. Use Color Converter for RGB, HSL or named-color input, then bring back its HEX value.
Eight-digit HEX includes alpha after the red, green and blue bytes. Some older applications accept only six digits; use an opaque color or a supported RGBA value there.
The field uses saturation and brightness in HSV. HSL is a separate output representation of the same sRGB color.
No. Values stay in this page’s memory. Reloading or leaving the tool starts a fresh workspace.
Enter a 3- or 6-digit opaque HEX value, then adjust hue and the color field. Set opacity separately if you need transparency. Copy the output format your destination accepts.
No. It makes transparency visible. The copied value contains color and, when applicable, alpha; it does not contain the checkerboard pattern.
Focus the color field and use arrow keys. Shift makes a larger adjustment; Home and End reach the field’s boundary positions. The numeric outputs let you review the resulting color.
