# Send Colors to your agent
Hand the extracted package to your coding agent with a concrete install brief instead of figuring it out manually.
## Fast path
- Download the package from Yavira.
- Extract it into a folder your agent can access.
- Paste one of the prompts below and point your agent at the extracted folder.
## Suggested prompts
### New install

```text
I downloaded a skill package from Yavira. Read SKILL.md from the extracted folder and install it by following the included instructions. Tell me what you changed and call out any manual steps you could not complete.
```
### Upgrade existing

```text
I downloaded an updated skill package from Yavira. Read SKILL.md from the extracted folder, compare it with my current installation, and upgrade it while preserving any custom configuration unless the package docs explicitly say otherwise. Summarize what changed and any follow-up checks I should run.
```

### Contrast Ratios (WCAG)

LevelNormal TextLarge Text (≥18pt or ≥14pt bold)UI ComponentsAA (minimum)≥ 4.5:1≥ 3:1≥ 3:1AAA (enhanced)≥ 7:1≥ 4.5:1—

Critical thresholds on white background:

#767676 → 4.54:1 ✅ barely passes
#777777 → 4.47:1 ❌ fails (cannot round up)
#757575 → 4.6:1 ✅ safe minimum gray

Pure colors on white:

Red #FF0000 → 4:1 ❌ fails for normal text
Green #00FF00 → 1.4:1 ❌ always fails (never use for text)
Blue #0000FF → 8.6:1 ✅ passes AAA

### Color-Only Information

Never rely on color alone to convey meaning. 8% of men have color vision deficiency.

<!-- ❌ Bad: only color differentiates states -->
<span class="text-green-500">Active</span>
<span class="text-red-500">Inactive</span>

<!-- ✅ Good: icon + text + color -->
<span class="text-green-500">✓ Active</span>
<span class="text-red-500">✗ Inactive</span>

Test designs in grayscale to verify information is still distinguishable.

### Semantic Color Tokens

Three-layer architecture for maintainable palettes:

/* Layer 1: Primitives (raw values) */
--blue-500: #3B82F6;
--gray-900: #111827;

/* Layer 2: Semantic (roles) */
--color-primary: var(--blue-500);
--color-text: var(--gray-900);
--color-error: var(--red-500);

/* Layer 3: Component (specific use) */
--btn-primary-bg: var(--color-primary);
--input-border-error: var(--color-error);

Name tokens by function, not appearance: text-primary not text-blue.

### Dark Mode

Create depth with luminosity, not shadows:

/* Light mode uses shadows for depth */
/* Dark mode uses surface brightness */
--surface-0: hsl(220 15% 8%);   /* page background */
--surface-1: hsl(220 15% 12%);  /* card */
--surface-2: hsl(220 15% 16%);  /* elevated element */
--surface-3: hsl(220 15% 20%);  /* modal */

Avoid pure black #000 and pure white #FFF as backgrounds. Use #0a0a0a and #fafafa to reduce eye strain.

### Neutral Grays

Add a subtle tint of your primary color to grays for cohesion:

/* Instead of pure gray */
--gray-100: hsl(220 10% 96%);  /* slight blue tint */
--gray-500: hsl(220 10% 46%);
--gray-900: hsl(220 10% 10%);

This creates a more polished, intentional palette.

### HSL for Variations

HSL makes generating consistent color scales trivial:

--primary-100: hsl(220 90% 95%);
--primary-300: hsl(220 90% 75%);
--primary-500: hsl(220 90% 55%);
--primary-700: hsl(220 90% 35%);
--primary-900: hsl(220 90% 15%);

Same hue and saturation, only lightness changes.

### Balance Rule

60-30-10 distribution:

60% dominant (backgrounds, containers)
30% secondary (cards, sections)
10% accent (CTAs, highlights)

Limit palette to 3-5 colors plus neutrals. More creates visual noise.

### Common Mistakes

text-gray-400 or lighter on white background typically fails contrast
Primary/accent colors for body text cause eye fatigue—use for headings and CTAs only
Hover states that only change opacity may fail contrast—change hue or lightness
Purple-to-blue gradients are an AI cliché—choose intentional combinations
Testing only light mode—dark mode often reveals contrast issues
Red/green as only differentiator—use icons or text labels alongside

### Safe Combinations

Avoid: red + green (colorblindness), adjacent hues (blue + purple), yellow + white (no contrast).
