Don't fear the Colorless blender ladies, just stamp some images on scrap paper, color them with your markers as normal and then use your blender to remove a little. The cherries were super easy because they are round and I've found the best way to "remove color" is in a circular motion. I also learned they are pronounced "CO-PICK", not "CAH-PICK" as I had been saying. Another tip is to use your color shades in threes. For instance, if you want browns to color dirt, sand, hair, coffee, etc then you should purchase in the same color coding (BV, B, Y, YR - color codings) and separate them by at least one digit. So E59-Walnut, E57-Light Walnut and E55-Light Camel. When coloring, you always start with the lightest color and work your way to the darker shades. If you want a more subtle effect, you would allow your first color shade to dry and then go over it again using the same color but just adding a bit more ink to certain areas.
I know this may sound confusing ladies but I assure you it's not. I'll try to work up some samples to show you later this week. Not feeling too creative at the moment, I just want my tea and some soup. ;)
