How to Adjust Image Hue Online

Our free online image hue adjustment tool allows you to easily shift the colors in any image with real-time preview. Whether you want to change the color tone, create artistic effects, or correct color casts, this tool provides instant results without requiring any software installation.

What is Image Hue?

Image hue refers to the color property that distinguishes one color from another on the color wheel. It's one of the three main properties of color, along with saturation and lightness. Hue adjustment shifts all colors in an image by the same amount around the color wheel, effectively changing the overall color tone while preserving the relative relationships between different colors.

How Our Hue Adjustment Tool Works

Our tool uses HTML5 Canvas technology to process your images in real-time. Here's how it works:

Upload Your Image: Simply drag and drop or select an image file (JPG, PNG, GIF, WebP) up to 10MB in size
Adjust Hue: Use the slider to shift hue from -180° to +180° (0° is the original color)
Real-time Preview: See changes instantly as you move the slider
Download Result: Save your hue-adjusted image in PNG format

Understanding Hue Values

The hue slider ranges from -180° to +180°:

-180° to -1°: Shifts colors counter-clockwise around the color wheel
0°: Original colors (no change)
1° to +180°: Shifts colors clockwise around the color wheel

When to Use Hue Adjustment

Hue adjustment is useful in many scenarios:

Color Correction: Fix color casts in photos (e.g., removing blue tint from indoor lighting)
Creative Effects: Create artistic color variations and mood changes
Brand Consistency: Match colors across different images for branding
Seasonal Adjustments: Change warm tones to cool tones or vice versa
Color Harmony: Create complementary or analogous color schemes
Photo Enhancement: Improve the overall color balance of images

Technical Details

Our tool processes images by:

Loading the image into an HTML5 Canvas element
Converting each pixel from RGB to HSL color space
Adding the hue shift value to the hue component
Converting back from HSL to RGB color space
Rendering the modified image data back to the canvas

The hue adjustment formula is: new_hue = (original_hue + hue_shift) % 360

Supported Image Formats

Our tool supports the following image formats:

JPEG (JPG): Most common format for photographs
PNG: Supports transparency and lossless compression
GIF: Animated and static images
WebP: Modern format with excellent compression
BMP: Uncompressed bitmap format

Tips for Best Results

Start Small: Begin with small hue adjustments (10-30°) and increase gradually
Consider the Subject: Different subjects respond differently to hue changes
Check Skin Tones: Be careful with portraits as extreme hue shifts can make skin look unnatural
Use Reset: The reset button quickly returns to the original image
Save Originals: Always keep a copy of your original image before making adjustments

Frequently Asked Questions

What is the difference between hue and saturation?

Hue refers to the color itself (red, blue, green, etc.), while saturation refers to the intensity or purity of that color. Hue adjustment changes the color tone, while saturation adjustment makes colors more vivid or muted.

Can I adjust hue on black and white images?

Hue adjustment has no effect on grayscale (black and white) images since they contain no color information. The tool will work, but you won't see any changes.

Will hue adjustment affect image quality?

Our tool processes images using high-precision calculations, so there should be minimal quality loss. However, some quality loss may occur due to the conversion between color spaces, especially with extreme adjustments.

Can I undo hue adjustments?

Yes! Use the reset button to return to the original image, or simply set the hue slider back to 0°. The original image is always preserved in memory.
