Parameters

​
saturation
integer
Adjust the intensity of colors in the image.Range: -100 to 100Default: 0
​

How it works

Bunny Optimizer provides multiple color manipulation tools: Saturation: Controls color intensity. Negative values desaturate (moving toward grayscale), positive values increase color vibrancy. Hue: Rotates colors around the color wheel. Every 33 units shifts to the next primary color in the spectrum. Contrast: Adjusts the difference between bright and dark areas. Positive values increase contrast, negative values reduce it. Tint: Applies a subtractive color overlay. The tint color is subtracted from the image, creating a color cast effect. Sepia: Converts the image to warm brown tones reminiscent of antique photographs.

​
Usage

​
Saturation adjustment

Control the intensity of colors in your image. Negative values desaturate toward grayscale, while positive values increase color vibrancy.
Comparison
A value of -100 produces a completely grayscale image. Useful for creating black and white photos, reducing oversaturated colors, or maintaining consistent color intensity across different source images.

​
Hue rotation

Rotate colors around the color wheel. The hue parameter shifts colors through the spectrum, with every 33 units moving to the next primary color.
Original colors
Perfect for color theme variations, creating stylistic effects, or adjusting color casts without affecting luminosity.

​
Contrast adjustment

Adjust the difference between bright and dark areas. Positive values make bright areas brighter and dark areas darker, while negative values flatten the tonal range.
Original contrast
Useful for making flat images pop, correcting overexposed or underexposed photos, or creating high-contrast stylistic effects.

​
Tint application

Apply a subtractive color tint over the image. The tint function works by subtracting the specified color from the image, creating a color cast effect.
Apply cyan tint
Ideal for creating mood-based color grading, maintaining brand color themes, or correcting color temperature issues. Use hex color codes without the # prefix.

​
Sepia effect

Apply a warm, brown-toned sepia effect reminiscent of antique photographs. The intensity ranges from 0 (no effect) to 100 (full sepia tone).
Apply sepia effect
Perfect for creating vintage aesthetics, nostalgic effects, or warm-toned artistic presentations.

​
Combining color adjustments

Color manipulation parameters work seamlessly together and with other Bunny Optimizer transformations:
Desaturate and increase contrast
Hue shift with brightness
Sepia with gamma correction
Tint and resize
Combine multiple adjustments to achieve precise color grading, correct multiple issues simultaneously, or create complex stylistic effects.
