Applying color and tone effects

CorelDRAW lets you apply color and tone to a bitmap. For example, you can replace colors, shift them between different color modes and adjust the brightness, lightness, and darkness of colors.

By applying color and tone effects, you can restore detail lost in shadows or highlights, remove color casts, correct underexposure or overexposure, and generally improve the quality of the bitmaps.

You can apply the following color and tone effects.

Effect Description

Hue-Saturation-Lightness Lets you adjust the color channels in a bitmap and change the position of colors in the spectrum. This effect allows you to change colors and their richness, as well as the percentage of white in an image.

Effect

Description

Color balance

Lets you add cyan or red, magenta or green, and yellow or blue to selected tones in a bitmap

Selective color

Lets you change color by changing the percentage of spectrum CMY process colors from the red, yellow, green, cyan, blue, and magenta color spectrums in a bitmap. For example, decreasing the percentage of magenta in the reds spectrum results in a color shift toward yellow.

Sample/Target balance

Lets you adjust color values in a bitmap with sample colors taken from the image. You can choose sample colors from the dark, midtone, and light ranges of an image and apply target colors to each of the sample colors.

Desaturate

Lets you reduce the saturation of each color in a bitmap to zero, remove the hue component, and convert each color to its grayscale equivalent. This creates a grayscale image without changing the color mode.

Level equalization

Lets you increase contrast by setting input values to map the darkest pixels in the bitmap to black and the lightest to white. You can decrease contrast so that all tones in a bitmap are represented by a specific tonal range.

Local equalization

Lets you enhance contrast near edges to reveal detail in both light and dark regions. You can set the height and width around the region to accentuate contrast.

Brightness-contrast-intensity

Lets you adjust the brightness of all colors and the difference between light and dark

Effect

Description

Gamma

Lets you accentuate detail in low contrast

areas without affecting shadows or

highlights.

Tone curve

Lets you perform color corrections precisely

by controlling individual pixel values. By

changing pixel brightness values, you can

make changes to shadows, midtones, and

highlights.
