Gradient Color Palette
How It Works
Create beautiful color gradients with these simple steps.
Step 1: Pick Start Color
Use the visual color picker to select your starting color. The HEX code syncs automatically as you adjust the picker.
Step 2: Pick End Color
Select the final color of your gradient. The blender will calculate all intermediate colors between these two endpoints.
Step 3: Set Steps Count
Specify how many color stops you want. Use 2-5 for distinct palettes or 15-50 for ultra-smooth gradient transitions.
Step 4: Copy & Export
Click any swatch in the result grid to copy its HEX code, or use the action buttons to copy all codes or the CSS gradient string.
Understanding Color Blending
Learn the fundamentals behind gradient color interpolation and how it applies to digital design.
Linear Interpolation
This tool uses linear interpolation (lerp) in RGB space. Each color channel is independently blended by a proportional factor between the start and end values.
RGB Color Space
Colors are mixed in the sRGB color model where each channel ranges from 0 to 255. This is the standard color space used by all web browsers and screens.
Step Factor Math
For N steps, each color at index i receives a blending factor of i/(N-1). The first color gets factor 0 (pure start) and the last gets factor 1 (pure end).
Midtone Behavior
When blending complementary colors like red and green, RGB interpolation can produce muddy midtones because it passes through desaturated territory in the color cube.
Color Cube Path
In a 3D RGB color cube, blending traces a straight line between two points. The path may pass through gray regions depending on the chosen start and end coordinates.
Hex Output Format
Every blended color is converted to a 6-digit HEX string (e.g., #FF5733). This format is universally supported across CSS, design tools, and programming languages.
CSS Gradient Equivalence
The generated palette is mathematically identical to a CSS linear-gradient with evenly spaced color stops at 0%, 100/(N-1)%, 200/(N-1)%, and so on up to 100%.
Perceptual Uniformity
RGB space is not perceptually uniform. Equal numerical steps do not always produce equal visual steps. OKLCH and CIELAB spaces solve this but produce non-HEX results.
Warm to Cool Transitions
Blending warm colors (reds, oranges) with cool colors (blues, greens) naturally passes through purples or browns depending on the specific RGB channel mixing ratios.
Lightness Preservation
When both start and end colors share similar lightness, the intermediate steps maintain that brightness level. Large lightness differences create visible brightening or darkening curves.
Saturation Dynamics
Intermediate colors can have lower saturation than either endpoint. This is most noticeable when blending colors on opposite sides of the RGB color wheel.
Data Visualization Use
Blended palettes are essential for heatmaps, choropleth maps, and continuous color scales where data values must map smoothly to a visual color range.
UI Theme Creation
Designers blend a brand color with white or black to generate complete shade scales (50-900) used in design systems like Material Design and Tailwind CSS.
Generative Art Applications
Artists use algorithmic color blending to create smooth gradients, aurora effects, and color fields in generative art systems like Processing and p5.js.
Print vs Screen Differences
RGB blending is designed for screens (additive light). Print uses CMYK (subtractive ink). Colors blended in RGB may appear different when converted for physical printing.
Animation Frame Interpolation
In CSS transitions and JavaScript animations, color changes are interpolated the same way this tool works by lerping RGB channels across each animation frame.
Key Features
Powerful gradient generation and export capabilities for designers and developers.
Dual Visual Pickers
Two built-in native color pickers let you precisely select start and end colors with real-time HEX code synchronization as you drag.
Custom Step Range
Generate anywhere from 2 to 50 intermediate colors giving you full control over gradient smoothness and palette size for any use case.
Click-to-Copy Swatches
Every color in the result grid is clickable. Tap any swatch to instantly copy its HEX code to your device clipboard with a single tap.
Full Gradient Preview
A wide preview bar renders the complete gradient at a glance showing exactly how it will appear when applied as a CSS background.
CSS Code Export
Copy a ready-to-use CSS linear-gradient string with all color stops pre-formatted. Paste directly into any stylesheet without edits.
Bulk HEX Copy
Grab all generated HEX codes at once in a clean newline-separated list perfect for pasting into design system files or documentation.
Palette File Download
Download a complete .txt file containing all HEX codes, start/end metadata, and the CSS gradient string for offline reference.
100% Client-Side Privacy
All blending math runs locally in your browser. No data leaves your device, no servers are contacted, and no colors are logged anywhere.

Frequently Asked Questions
Find answers to common questions about color blending and gradients.
What is color blending?
Color blending calculates intermediate colors between two endpoints using linear interpolation. Each RGB channel is independently mixed by a proportional factor producing a smooth transition from the start color to the end color.
How many steps should I use for my gradient?
For a discrete color palette 3-8 steps work best. For smooth CSS background gradients 10-20 steps give excellent results. The maximum 50 steps produces near-seamless transitions suitable for data visualization.
What format are the output colors in?
All colors are output in HEX format (e.g., #FF5733). HEX is universally supported across web design, Figma, Photoshop, and all programming languages.
Can I use the CSS gradient code directly?
Yes. Click the "Copy CSS" button to get a ready-to-paste CSS linear-gradient string. It works with background, background-image, and any CSS property that accepts gradient values.
Why do some gradients look muddy in the middle?
How do I download or export my palette?
Click "Download" to save a .txt file with all HEX codes and the CSS gradient string. You can also click any swatch to copy individual codes or use "Copy All HEX" to grab everything at once. For visual palette management import into Coolors or Adobe Color.
Can I blend more than two colors?
This tool focuses on precise two-color blending. For multi-stop gradients with 3 or more colors use CSSGradient.io which supports unlimited color stops with live CSS code output.
Is my data stored or sent anywhere?
No. All calculations happen entirely in your browser using JavaScript. Nothing is sent to any server, no cookies are set, and no color choices are logged. It is completely client-side processing.
