Colorize Image
Tint a photo with a chosen color.
How to use Colorize Image
Free colorize tool: wash a picture in any hue you pick while keeping its light and dark detail.
Open Colorize Image on toolpermarket, then enter the values you want to work with.
In the Image field, open a photo to tint. Grayscale or low-color images tint most cleanly.
In the Tint color field, pick any hue to wash the picture. A mid-tone color gives the richest duotone.
Press Colorize to compute the result. The output appears immediately below the form. Tweak any field and run it again to check a different scenario.
Read the result and use it as needed. If the number looks off, re-check your inputs and run it again — the math is deterministic, so the same entries always return the same answer.
Worked example. A neutral cityscape washed in teal reads as a cohesive duotone poster.
Tips for accurate results.
Start from a desaturated image for clean tints.
Use brand colors for themed graphics.
Keep luminance detail by avoiding pure black tints.
When to use Colorize Image. Building a duotone effect for branding. Theming a photo to match a palette. Unifying a mixed set of images.
When you actually reach for this
- You want to tint a grayscale or flat image toward a specific color.
- You need a duotone or themed look for a design.
Where this tool stops being accurate
- At full strength the tint overrides original hues while keeping lightness, so the source colors barely show.
- Colorize is not a precise recolor; use it for mood, not for matching a brand swatch exactly.
Frequently asked questions
How is the tint applied privately?
The photo is read in the browser, drawn to the canvas, then composited with your chosen color in color mode so the hue and saturation come from the tint while the original light and dark structure is kept. Everything runs locally and the colorized file is downloaded from the canvas.
Why does my detail survive the tint?
The color blend mode preserves the luminance of the source, so shadows stay dark and highlights stay light even as the hue shifts. That is what gives a true duotone look instead of a flat color wash that buries the picture.
Can I colorize a color photo?
You can, and it will push the whole image toward your tint while still respecting its brightness. For the cleanest duotone, start from a grayscale or low-saturation image so the tint reads as the dominant color rather than mixing with existing hues.
Will colorize match my exact brand color?
Roughly, by lightness. It tints toward the color rather than remapping each pixel, so verify the result against the swatch.
