Terminal Color exploration using the Ansipixels TUI go library.
tcolor is a simple terminal/TUI color picker/chooser/explorer.
Multiple modes (space bar and arrows to switch) from basic named colors, to 256 indexed:
Hue, Saturation, Lightness:
3 RGB screens, eg:
Saved (clicked) colors on exit (and similar if you pass in colors as arguments):
You can get the binary from releases
Or just run
CGO_ENABLED=0 go install fortio.org/tcolor@latest # to install (in ~/go/bin typically) or just
CGO_ENABLED=0 go run fortio.org/tcolor@latest # to run without install
or even
docker run -ti fortio/tcolor # but that's obviously slower
or
brew install fortio/tap/tcolor
With no arguments/only flags:
Currently 4 interactive screens (3 sub-screens in RGB):
- Basic 16 colors
- 256 Colors
- 24 bits Hue Saturation Luminance (HSL)
- 24 bits RGB where space bar change which component is set up/down with arrows. Space bar to switch component.
Up and down arrows to increase luminance on the HSL screen, the third color component on the RGB screen.
Move the mouse for color details.
Click to copy the color code to the clipboard. They are also saved to be printed on exit (Q). If using a modifier or right clicking, the web HSL is copied instead of the #RRGGBB format.
If you pass arguments to tcolor they will be decoded as colors and previewed, with various formats like
c101 # 101th color of the 256 palette
red # Name from the 16th basic color (+ Orange 17th named color), see list in first screen.
RRGGBB # 6 hex RGB
0.1,.4,.5 # float [0-1] hsl color
hsl(300 40 50) # web css HSL format (degrees percentSaturation percentLightness)
HSL#FFF_FF_200 # full resolution hex hsl (000-FFF hue, 00-FF saturation, 000-3FF lightness)
# and more...tcolor helpflags:
-rounding int
Number of digits to round HSL values for WebHSL output/copy paste (negative for default full precision) (default -1)
-truecolor
Use true color (24-bit RGB) instead of 8-bit ANSI colors (default is true if COLORTERM is set) (default true)
