I look at your art sometimes and think that if it was ever colored, the charm of the black and white visual impact would be totally lost. I have never looked at your pics and ever thought that color would greatly bolster the image, almost the opposite. You have a way of illustrating in black and white that tells the story without the need for flashy tones, you know when to add heavy black, or to just leave an area as line art. I envy your talents Mr Cluedog.
I must agree here. A few of the less-detailed transformation sequences would look okay colored (I've seen one or two that someone else colored, and they did, although it did blunt their charm a little), but things like this are best left as they are.
Some stuff is drawn with being colored in mind, so you find yourself saying, 'that'll look excellent when it gets some color,' but some stuff just feels forced and awkward when colored unnecessarily. It's quite a talent to create a black and white image, and make it stand out without using or needing color.
I did see a recently colored image of Cluedogs [link] and felt that it didn't enhance or improve upon the usual b/w style in any way. I don't mean to knock the colorist, as she did a good job, but that was my gut feeling.
