tpick

Tpick is a tui color picker because I was not satisfied with the available color pickers.

None of them have a way to select with HSL except for this one but that's a neovim extension which is clunky.

Usage

Currently there are no cli options.

Terms

• Input format, the format used for inputting a color
• Selection format, the way that selecting a color is done, eg: rgb, hsl
• Output format, the color format used for outputting

Controls

Control	action
l	increase current value
L	increase current value by 10
h	decrease current value
H	decrease current value by 10
0-9	set current value to 0%-90%
$	set current value to 100%
o	cycle output format
O	Various output format options
i	cycle input format
I	Input a number for the selected slider
y	copy output
Y	copy ONLY the output value with no extra formatting
p	Paste color from clipboard (can be any supported format)
a	Enable/disable alpha channel
n	Input a new color
q	quit
<CR>	quit and copy to clipboard

Variables

• 0 <= R <= 255 (red)

• 0 <= G <= 255 (green)

• 0 <= B <= 255 (blue)

• 0 <= A <= 255 (alpha)

• 0 <= H <= 360 (hue)

• 0 <= S <= 100 (saturation)

• 0 <= L <= 100 (lightness)

Supported Input formats

• rgb(R, G, B)
• rgba(R, G, B, A)
• hsl(H, S, L)
• hsla(H, S, L, A)
• \x1b[38;2;R;G;Bm
• R;G;B
• #RGB #RGBA #RRGGBB #RRGGBBAA

Supported Selection Formats

• hsl
• rgb

Supported Output Formats

• rgb(R, G, B)
• rgba(R, G, B, A)
• hsl(H, S, L)
• hsla(H, S, L, A)
• #RRGGBB
• #RRGGBBAA
• \x1b[38;2;R;G;Bm

Configuration

See the example config

Goals

• Swap between different selections
  • HSL
  • RGB
  • CYMK not really useful
  • ANSI 256 color selection pannel
• Ability to input number for slider
• Custom output formats that can be used with convert/-o
• Swap between different outputs
  • Let user pick from some kind of menu instead of cycling (or both)
  • Option to display all outputs at once
  • Custom output formats
  • Show multiple different custom output formats
    • This is unecessary as different formats can be seperated with %n (a new line)
• Swap between different output cycles
• Specify starting value with cli option
  • Read starting value from stdin
• Copy output
• Convert any supported format to any other supported format via cli.
• Pressing a key to input a color
• Cli options for setting default Selection/Output formats
• Event system
  • would write to some kind of fifo/socket file that a shell script can read from
  • events would include:
    • color change
    • on color copy
    • selection type changed
• Config file
  • Custom output formats
  • Keybindings
• Multiple color previews to allow color comparisons

Maybe goals

• Saving colors
• Using the kitty keyboard input standard

Non Goals

• supporting non 24bit (truecolor) terminals.
