Use the Colorize command to tint vector objects with solid color fill or pen inks when you want to mix two colors, or shade one color with another. Doing this in the Presets palette can be complicated, since you have to create a custom color and set the correct values to approximate a two-color mixture. The Colorize command lets you simply select two colors and choose the percentage of each.
Canvas X Draw uses the specified percentages to determine the new color values for the selected object. For each color value (e.g., Red, Green, and Blue in the RGB color model), Canvas X Draw finds the difference between the tint and the original color. Then, Canvas X Draw multiplies the differences by the percentage you specify, and adds these values to the original color values.
An object’s color has a red value of 40%. To tint 50% with a color that has a red value of 100%, Canvas X Draw calculates a new red value of 70%. The same calculations apply to the green and blue values for an RGB color.
Difference in red values: 100 - 40 = 60
Value difference multiplied by tint percentage: 60 * 50% = 30
Original color value plus tint value is new value: 40 + 30 = 70% red
