Overview
Introduction
This tool generates a clean, evenly-stepped set of colors between exactly two hex colors you choose, rendered as a strip of swatches with hex codes, entirely in your browser.
It's the simplest way to see (and reuse) a handful of shades that gradually transition from one color to another.
What Is Color Step Generator?
A pure pixel generator that linearly interpolates RGB values between a start color and an end color at a chosen number of evenly-spaced steps, then renders each step as its own solid 64x64 pixel swatch.
The generator also returns the exact hex code for every step, so the colors can be copied directly into design tools or code.
How Color Step Generator Works
After validating both hex colors and the step count, the tool computes, for each step index, a fractional position between 0 (color A) and 1 (color B).
Each step's RGB value is linearly interpolated between the two colors at that fraction, then painted as a uniform 64x64 square into the output strip, with the resulting hex codes collected alongside the image.
When To Use Color Step Generator
Use it whenever you need a small, evenly-graduated set of shades between two specific colors, such as building a hover/active state ramp for a UI element.
It's also useful for quickly visualizing how many perceptible steps exist between a light and dark version of the same color.
Often used alongside PNG Gradient Palette Generator and Multi-color Gradient PNG Creator.
Features
Advantages
- Produces exact, reusable hex codes for every intermediate step, not just a visual reference.
- Guarantees the first and last swatches exactly match your input colors, with no rounding drift.
- Runs entirely client-side with no external dependencies.
Limitations
- Only supports interpolating between exactly two colors; for more than two stops, use the Gradient Palette Generator instead.
- Swatches are always a fixed 64x64 pixel size in a single horizontal row.
Examples
Best Practices & Notes
Best Practices
- Use an odd number of steps (like 5 or 7) when you want a clean middle swatch exactly halfway between the two colors.
- Copy the returned hex codes directly for pixel-perfect reuse rather than eyeballing colors from the image.
Developer Notes
The two-color interpolation and swatch-rendering logic is a pure, DOM-free lib function operating on a plain pixel buffer, with its own local swatch-strip renderer independent of the other palette tools, keeping it fully unit-testable in isolation; only the component paints the result onto a <canvas>.
Color Step Generator Use Cases
- Building a UI hover/active/disabled color state ramp
- Creating a simple two-color gradient reference swatch set
- Generating grayscale or tint/shade steps from a single base color
Common Mistakes
- Requesting more than 2 colors — this tool strictly takes exactly a color A and a color B, not a list.
- Expecting non-uniform spacing — all steps are always evenly spaced fractions between the two colors.
Tips
- Use a high step count (16-32) when you need a smooth-looking ramp for something like a slider track.
- Pair with the Multi-color Gradient PNG Creator if you decide you want a fully continuous version of the same two-color blend.
