Removing R from RGB Color
<p>Is there a way to remove the <strong>red</strong> channel of an <strong>RGB</strong> pixel in a way such that in the resulting picture the red color goes to <strong>white</strong> not to black? I need to distinguish between red color and blue/black color, but in different light the <strong>RGB</strong> value varies. If I simply remove the <strong>R</strong> channel, darker red colors become black and I want the opposite result.</p>

<p>Thanks!</p>
