About hColorPicker

hColorPicker is a lightweight, simple color picker — like extracting just the color picker from Photoshop — that lets you quickly select colors and copy their color codes. I created it because launching Photoshop every time I needed to pick a color while building websites felt like overkill.

Simple Color Selection

Simple window

It’s a straightforward window for choosing a color and outputting its color code — nothing more, nothing less.

Wide Range of Color Code Formats

You can instantly copy the selected color to the clipboard in various formats:

Color code output

HEX #RRGGBB / RRGGBBAA (depends on whether “Prefix HEX with #” is checked)
RGB R, G, B
RGBA R, G, B, 255
CSS rgb(R, G, B)
JSON {"r":R,"g":G,"b":B}
Array [R, G, B]

ACO File Format Support

ACO file format support

hColorPicker supports reading and writing ACO files developed by Adobe.

ACO files are color palette (swatch) files that let you save sets of colors you want to keep as a single file.

You can download and load color palette files published on Adobe Stock or by designers.

ACO file versions up to ver.2 are supported — all versions can be read and written.

You can also create your own color swatch files (ACO files) from scratch. Simply select a palette slot and use hColorPicker’s color selector to apply the color.
