## Description

Building a cohesive brand palette shouldn't feel like guesswork. This MCP connects your AI client directly to an expert color theory engine that moves beyond simple RGB mixing. It ensures every generated shade works together visually, using the sophisticated OKLCH color space so colors look consistent across all screens and mediums.

You can generate foundational palettes based on classic relationships like complementary or triadic schemes. Need depth? Generate shades from a single hue to create rich gradients. If you're building for the web, it guarantees accessibility standards with one function. For complex UI/UX needs, it even allows you to systematically vary only one color attribute while holding others constant. When paired with Vinkius, you get access to this high-level design tool alongside thousands of other workflows.

## Tools

### get_accessible_palette
Produces a palette where all colors pass WCAG AA contrast standards, guaranteeing web readability.

### get_harmony_palette
Generates color palettes based on standard theory relationships like complementary or triadic schemes.

### get_monochromatic_shades
Creates a sequential range of shades and tints derived from one single chosen hue.

### get_attribute_variation
Generates palettes by maintaining a constant value for one color property while systematically varying another.

## Prompt Examples

**Prompt:** 
```
I need a palette starting with #ff5733 that works great in dark mode and passes AA contrast.
```

**Response:** 
```
**🎨 Accessible Palette Generated 🎨**

| Color | Hex Code | WCAG Status | Use Case |
| :---: | :---: | :---: | :---: |
| Primary | `#FF5733` | Pass (AA) | Background/Accent |
| Text Dark | `#1A1A1A` | Pass (AAA) | Body Copy |
| Accent Light | `#F0F0F0` | Pass (AA) | Cards/Separators |

*Tip: Use the contrast checker to verify all text elements against this set.*
```

**Prompt:** 
```
Give me a monochromatic palette for a deep forest green, showing 5 steps.
```

**Response:** 
```
**🍃 Monochromatic Shades (Forest Green) 🌿**

Here are five systematic shades derived from your base color (`#27ae60`), perfect for creating subtle depth in backgrounds or gradients:

*   **Deepest Tone:** `#1e8449` (Best for headers)
*   **Tone 2:** `#27ae60` (Primary use tone)
*   **Mid-tone:** `#a8e6cf` (Secondary elements)
*   **Light Tone:** `#d4efdf` (Dividers/Borders)
*   **Softest Tint:** `#ffffff` (Background base)
```

**Prompt:** 
```
Generate a palette based on complementary colors starting from this blue: #3498db.
```

**Response:** 
```
**🤝 Complementary Harmony Pairings 🤝**

Based on your input (`#3498db`), here are two mathematically complementary hex codes. This pairing is ideal for creating high visual contrast between primary and secondary actions:

*   **Base Color:** `#3498db` (Primary Action)
*   **Complementary Accent:** `#db7534` (Secondary Action/Highlight)

These colors maintain excellent perceptual separation, making your UI highly directional.

## Capabilities

### Generate accessible palettes
Creates a palette guaranteed to pass WCAG AA contrast standards, ensuring your website is readable for everyone.

### Build traditional color schemes
Generates mathematically correct color combinations based on classical theory rules like complementary or analogous relationships.

### Create single-hue depth ranges
Develops a full range of shades and tints derived systematically from one base color.

### Systematically vary color attributes
Generates palettes by keeping one property (like chroma) constant while varying another (like lightness), allowing for precise design control.

## Use Cases

### Building an Accessible Landing Page
A designer needs a primary color but fears it will fail contrast checks. They prompt their agent to use get_accessible_palette, getting instant confirmation that the resulting palette passes WCAG AA standards for both text and background.

### Defining Brand Primary Colors
A brand manager needs a strong set of core colors but only has one hex code. They use get_harmony_palette to generate reliable complementary and triadic options that fit their brand's established mood.

### Creating Gradient Systems
A developer is building a hero section gradient. Instead of picking random stops, they run the base color through get_monochromatic_shades to generate mathematically perfect steps for smooth visual depth.

### Designing Themed UI Components
An engineer needs several states (e.g., 'selected,' 'hovered,' 'disabled') using a single base color. They use get_attribute_variation to adjust only the lightness while keeping chroma consistent, maintaining brand integrity across all components.

## Benefits

- WCAG Compliance: The get_accessible_palette tool guarantees that your color choices meet AA contrast standards, eliminating legal and usability risks right out of the gate.
- Theory-Driven Output: Stop guessing. Use get_harmony_palette to generate reliable palettes based on established relationships like split-complementary or analogous schemes.
- Depth Control: Need subtle variations? get_monochromatic_shades handles creating smooth, consistent ranges from a single base color without you having to do the math.
- Precision Variation: The get_attribute_variation tool gives designers granular control by letting you vary only one color property while holding others constant, which is critical for complex UI components.
- OKLCH Science: By working in the OKLCH space, this MCP ensures that colors look consistent and uniform regardless of screen calibration or viewing conditions.

## How It Works

The bottom line is you get precise, professional palettes without ever needing to manually calculate color ratios or check contrast levels.

1. You tell your AI client what kind of palette you need, such as a complementary scheme or shades from a specific color.
2. The MCP processes the request using advanced color science (OKLCH), ensuring the mathematical relationships between colors are accurate and perceptually uniform.
3. Your agent returns structured data containing hex codes, RGB values, and WCAG compliance checks for your new palette.

## Frequently Asked Questions

**How does the Palette Generator MCP handle accessibility and contrast?**
It guarantees compliance using get_accessible_palette. When you request a palette, it checks every shade against WCAG AA standards, ensuring your design is readable for users with visual impairments.

**Do I need to know color theory to use the Palette Generator MCP?**
No. You just tell your agent what relationship you want—like 'triadic' or 'complementary.' The tool handles the complex math, so you get professional results instantly.

**Can I create gradients using this MCP?**
Yes. By using get_monochromatic_shades, you can generate a perfectly smooth gradient sequence from one base color to various shades and tints needed for background depth or progress bars.

**What if my brand colors aren't standard? Can the MCP still help?**
The MCP works with any starting hex code. It then uses advanced science (OKLCH) to generate mathematically correct variations, like using get_attribute_variation to keep your core hue while changing its perceived lightness.

**Is the palette generated by the Palette Generator MCP suitable for print or just web?**
The tool uses advanced color science that works across different mediums. While hex codes are for screen use, the structured output gives you a scientific basis to translate those concepts into CMYK for professional printing.
