anytocbpng

anytocbpng is an image filter that gives you an idea of what red-green
colorblind people see. We will never know exactly what it looks like to them,
but this filter gives you a very accurate picture of what colors they can tell
apart, etc..

You are free <ldownload anytocbpng<>, share it, change it etc.... it's <lfree
software<>! (It's licensed under the <lGNU GPL<>.)

The trouble with red/green colorblindness is that red and green are
indistinguishable. So <lJason Woofenden<> wrote this little program to average
the red and green values for each pixel, thus creating an image where red and
green are indistinguishable.

This process results in the following color palette:

<ianytocbpng_palette.png<>

I think this is most eye opening if you first take a good look at the
resulting image. Then look at the original. You may be surprised.

Here's a picture of a caterpillar that has been filtered:
