JUst turn off the green and blue channels!

Code: Select all

convert image.png -color-matrix '1,0,0  0,0,0  0,0,0' result.png

This has the same effect as using +level-colors ,red a straight linear white to red modification of RGB values.

however is this what you want? You may get a better result by doing the level on a grayscale image!

Code: Select all

convert image.png -type grayscale +level-colors ,red result.png

Or doing both operations together using some varient of...
convert image.png -color-matrix '.2 .5 .3 0,0,0 0,0,0' result.png
