Color Burn
Color Burn intensifies the dark areas in each image. Whites in the background image
replace the foreground image, while whites in the foreground image become transparent.
Midrange color values in the background image allow midrange color values in the
foreground image to show through.
Lighter midrange color values in the background image allow more of the foreground
image to show through. Darker midrange values in all visible overlapping areas are then
mixed together, resulting in intensified color effects.
The order of two objects affected by the Color Burn blend mode is important.

Linear Burn
Similar to Multiply, except that darker overlapping midrange color values are intensified,
like Color Burn. Progressively lighter color values in overlapping images become
increasingly translucent, allowing darker colors to show through. Whites in either image
allow the overlapping image to show through completely.
The order of two objects affected by the Linear Burn blend mode does not matter.
