Yesterday I had a huge scanned map (not a GIS funcational map) in which I was supposed to replace the outer, light aqua areas with a color that was different than the water which is a little darker blue. I got this project, it had to be done in 15 min, needless to say I thought it was a cinch but when I went to select 'similar' it ended up selecting all the blues, no matter what value I put in the tolerance. I also looked at the channels and copying the layers on top of one another with different blending modes to see if I could isolate this lighter aqua layer without selecting the major waterways. I ended up doing it all my separate selections today (took me 4 hours) but was hoping there was another way so I don't get caught with my pants down next time. Oh, and I also used the 'replace color' feature and it again selected the whole water, (light and dark blue).
