colorto

User and agent friendly CLI to convert colors between formats.

Agent Skill

Add the color conversion skill to your agent:

npx skills add https://github.com/constantgillet/colorto --skill convert-color

Installation

npm install -g @cgillet/colorto

Usage

Direct conversion

colorto "#ff6347" --format=oklch
# ██  oklch(0.6962 0.1955 32.32)

Short flag:

colorto "#ff6347" -f rgb
# ██  rgb(255, 99, 71)

Interactive mode

Run without --format to pick from a list:

colorto "#ff6347"
# ? Convert to
# ❯ HEX    #ff6347
#   RGB    rgb(255, 99, 71)
#   HSL    hsl(9, 100%, 64%)
#   HWB    hwb(9 0% 0%)
#   LAB    lab(62% 57 39)
#   LCH    lch(62% 69 34)
#   OKLAB  oklab(0.63 0.16 0.07)
#   OKLCH  oklch(0.63 0.18 29)

Any input format works

colorto "rgb(255, 99, 71)" -f hex
# ██  #ff6347

colorto "hsl(9, 100%, 64%)" -f oklch
