This evidence comes from the upstream catalog. This site has not installed, run, or security-reviewed the plugin.

Install

Start with a prompt that asks an agent to review the GitHub repository and source. Switch to the command if you want to install it yourself.

Copy this prompt into DSH, Codex, or another agent and ask it to review the GitHub repository and source first.

Do not install or run any commands yet. Read this plugin's GitHub repository, README, and relevant source code. Then answer the questions below clearly and directly so I can decide whether it fits my needs:

1. What is this plugin, and what problem does it solve?
2. Who is it for, and what are its typical use cases?
3. How is it used after installation? Include one minimal example.
4. What known limitations or privacy, security, compatibility, or maintenance risks does it have?
5. Give a clear recommendation: recommend, conditionally recommend, or do not recommend, with reasons.

Distinguish statements documented by the repository, inferences from source code, and unknowns. If evidence is insufficient, say so explicitly. Do not guess or simply repeat the README.

dsh-color

Color conversion toolbox for DeepSeek Harness (dsh): parse and convert any CSS color, evaluate WCAG contrast, and look up CSS color names.

Pure local math — zero runtime dependencies, no network, no side effects.

Tools

ToolDescription
convert_colorParse any CSS color (hex #rgb/#rgba/#rrggbb/#rrggbbaa, rgb()/rgba(), hsl()/hsla(), hwb(), CSS color names) and convert it to hex / rgb / hsl / hwb — or all formats at once
contrast_ratioWCAG 2.x contrast ratio between two colors with AA/AAA verdicts for normal or large text (WCAG 1.4.3 thresholds)
color_infoCSS named-color lookup: search by name substring ("blue" → blue, blueviolet, lightblue, …) or by exact value (aqua ≡ cyan), with hex/rgb/hsl/luminance per match

Install

dsh plugin --profile web add github:TYEclipse/dsh-color

Replace web with your profile name (dsh plugin has no default profile).

Usage examples

convert_color("rebeccapurple")
  → hex #663399, rgb(102, 51, 153), hsl(270, 50%, 40%), hwb(270 20% 40%)

convert_color("#ff000080", format: "hex")
  → #ff000080 (alpha preserved)

contrast_ratio("#777777", "#ffffff")
  → ratio 4.48 — fail for normal text, AA for large text

contrast_ratio("white", "hsl(0, 100%, 50%)")
  → ratio 4.0 — AA for large text only

color_info(query: "blue", limit: 5)
  → blue #0000ff, blueviolet #8a2be2, cadetblue #5f9ea0, …

color_info(query: "#00ffff", by: "value")
  → aqua, cyan (both map to #00ffff)

Feature notes

  • Input formats: hex shorthand/full (3/4/6/8 digits), legacy comma syntax

(rgb(255, 0, 0)) and modern space syntax (rgb(255 0 0 / 50%)), percentages (rgb(100% 0% 0%)), angle units for hue (deg/rad/grad/turn), all 148 CSS Color Module Level 4 named colors, and transparent.

  • Alpha is preserved through every conversion; hex output switches to

8-digit form only when alpha < 1.

  • WCAG math: relative luminance per WCAG 2.x (sRGB linearization), ratio

(L1+0.05)/(L2+0.05), thresholds AA 4.5 / AAA 7 for normal text and AA 3 / AAA 4.5 for large text (≥18pt or ≥14pt bold).

  • Out-of-range channels are clamped (modern CSS behavior).
