Colorize Black and White Photo Online

How the Color Estimate Is Made

This browser effect maps grayscale pixels to approximate hues. It reads pixel tone, nearby variation, and image position; it does not recognize people or objects.

1. Read grayscale tone

Pixel brightness becomes the lightness of its output color.

Dark Midtone Light

2. Estimate a hue

Nearby tonal variation and vertical position influence the approximate palette.

Blue Green Warm

Illustrative hue families only—not recognized objects or recovered historical colors. Compare the estimate with your original and keep the source file.

How to Use Colorize B/W

  1. Upload a grayscale or sepia photo. A clear source with visible light and dark tones gives the pixel-based effect useful tonal information.
  2. Apply the estimated color effect. Select Apply Color Effect. The browser maps approximate hues from pixel brightness, nearby variation, and vertical position.
  3. Compare and download. Review the estimate against the original, then download it or reset. The result does not recover original colors.

What the Tool Can—and Cannot—Do

Colorize B/W uses a rule-based browser effect, not scene recognition. It cannot tell a face from a shirt or sky, choose historically verified colors, remove scratches, or restore missing detail. Treat its palette as a creative interpretation.

Brightness mapping
Pixel brightness becomes the lightness of the assigned hue.
Tone and position influence hue
Nearby pixel variation and vertical image position also affect the estimate.
No manual color controls
There is no preset selector, paint brush, or object mask on this page.
Keep the original
Original colors cannot be reconstructed from grayscale values; compare both versions before sharing.

Frequently Asked Questions

Does it recover the original colors?

No. Grayscale pixels do not contain their original hues. This effect estimates color from brightness, nearby variation, and image position.

Can I choose a style or paint a specific object?

No. The current tool applies one automatic mapping and has no style selector, manual color brush, or object mask.

Will colorizing repair damage?

No. It changes pixel colors but does not remove scratches, fix tears, or recreate missing detail.
