How to use the CCSprite Color value to color sprites at runtime.


The CCSprite class contains a Color property which can be used to color or tint a sprite dynamically.

Code Example

The following code creates a CCSprite grid, as might be used in a block breaking game:

CCColor3B[] rowColors = new CCColor3B[]
    new CCColor3B(100, 100, 255), // blue
    new CCColor3B(150, 150, 255), // light blue
    new CCColor3B(150, 255, 150), // light green
    new CCColor3B(70, 255, 70), // green
    new CCColor3B(255, 255, 0), // yellow
    new CCColor3B(200, 150, 0), // orange
    new CCColor3B(255, 70, 70), // red

for(int row = 0; row < rowColors.Length; row++)
    for (int column = 0; column < 10; column++)
        var sprite = new CCSprite("Images/grayscale.png");
        sprite.Color = rowColors[row];
        sprite.PositionY = 170 - row * sprite.ContentSize.Height;
        sprite.PositionX = 20  + column * sprite.ContentSize.Width;


The code above produces the following result:

The code above uses the grayscale.png image:

The Math Beind Coloring

The Color value on a CCSprite is applied by multiplying the CCSprite.Texture by the Color value. For example, assigning a CCColor of new CCColor3B(255, 0, 0) will remove all green and blue from the CCSprite, leaving behind only the red component of each pixel. Since colors cannot be added using the Color property, grayscale images provide the most flexibility for recoloring.
