Color Balance
Upload an image to adjust the color balance.
What is the Color Balance Tool?
The Color Balance tool is an online image editing tool that adjusts the balance of colors by individually controlling the RGB (Red, Green, Blue) channels of an image. You can adjust the color tone of photos to be warmer or cooler, remove color casts, and transform images to your desired mood.
Automatically correct colors with a single click using the auto white balance feature, or precisely correct colors by specifying white/gray areas with the eyedropper. It works directly in your browser without installation, and all processing is done locally to keep your privacy safe.
Use Cases
- Indoor Lighting Color Correction – Remove yellow or blue tints from photos taken under fluorescent or incandescent lights and correct them to natural colors.
- Landscape Photo Atmosphere – Make sunset photos warmer and ocean photos fresher to maximize the atmosphere.
- Product Photo Color Correction – Match the colors of e-commerce product images closer to the actual product to increase customer satisfaction.
- Skin Tone Correction – Adjust skin tones in portrait photos when they appear too red or yellow to natural tones.
- Vintage/Retro Effects – Easily apply vintage atmosphere or film camera-like colors using presets.
- White Balance Error Fix – Correct photos where the camera’s white balance setting was wrong and the overall color is off.
Key Features
- Individual RGB Channel Control – Adjust Red, Green, Blue channels independently in a range from -100 to +100 for precise color control.
- Auto White Balance – Uses the Gray World algorithm to automatically analyze the color balance of an image and apply optimal correction values.
- Eyedropper White Point – Click directly on an area that should be white or gray in the image, and the entire image color will be corrected based on that point.
- 6 Presets – Apply commonly used color combinations like Warm, Cool, Vintage, Fresh, Sunset with one click.
- Real-time Preview – See results instantly as you adjust the sliders for intuitive editing.
- Original Compare Mode – Compare the original and edited result side by side to clearly see the changes.
- 3 Download Formats – Save in your preferred format: PNG (lossless), JPEG (compressed), or WebP (modern).
- Drag and Drop – Start editing immediately by simply dragging and dropping an image without file selection.
How to Use
- Upload Image – Click to select an image or drag and drop to upload.
- Choose Color Adjustment Method – Directly adjust RGB sliders, click the auto white balance button, or specify a reference point with the eyedropper.
- Use Presets (Optional) – Click preset buttons like Warm or Cool to quickly change the mood.
- Check Result – Check the result with real-time preview and compare changes with the original compare button.
- Download – When satisfied, click the download button and select your preferred format (PNG/JPEG/WebP) to save.
Understanding Color Balance
What are RGB Channels?
Digital images express all colors through a combination of three color channels: Red, Green, and Blue. Each pixel has a value between 0-255, and the combination of the three channels can create approximately 16.7 million colors.
How Channel Adjustment Works
- Increasing Red Channel – The image becomes warmer with a reddish tone. Decreasing it makes the cyan (blue-green) tone stronger.
- Increasing Green Channel – The image takes on a greenish tint and feels more natural. Decreasing it makes the magenta (red-purple) tone stronger.
- Increasing Blue Channel – The image becomes cooler with a bluish tone. Decreasing it makes the yellow tone stronger.
Auto White Balance Algorithm
This tool uses the Gray World algorithm. This algorithm is based on the assumption that “an average scene should be gray,” and calculates the RGB average values of the image to correct the three channels to be equal. It works effectively for most typical photographs.
Eyedropper White Point
The eyedropper function corrects the entire image color based on the area the user specifies as “this should be white or gray.” Clicking on areas that should be color-neutral, such as white paper, gray walls, or snow, allows for accurate correction.
Frequently Asked Questions
Should I use auto white balance or the eyedropper?
Auto white balance is quick and effective for general color shifts. However, if the image contains a lot of specific colors (e.g., sunset photos, forest photos) or if the automatic result is not satisfactory, it’s more accurate to directly specify a white/gray area with the eyedropper.
Can I make further adjustments after applying a preset?
Yes, presets are just a starting point. After applying a preset, you can further adjust the RGB sliders to fine-tune to your desired color tone.
Which download format should I choose?
PNG uses lossless compression for the highest quality but has larger file sizes. JPEG has smaller file sizes suitable for web sharing. WebP combines the advantages of both PNG and JPEG, offering high quality and small file size, but may not be supported by some older programs.
What area should I select when clicking with the eyedropper?
Click on areas that should actually be white, gray, or neutral in color. For example, white paper, white shirts, gray concrete, snow, clouds are good reference points. Avoid areas that are too dark or have strong colors.
Are my images stored on the server?
No, all image processing is done only within your browser and is not uploaded to any server. When you close the page, the images are completely deleted, keeping your privacy safe.
Why is the RGB value range from -100 to +100?
The slider value is added to or subtracted from each pixel’s RGB value (0-255). +100 increases that channel by up to 100, and -100 decreases it by 100. The resulting value is always kept within the 0-255 range.
