This article seems to lend veracity to my thought that your are my other-brother-from-the-land-down-under.
It always amazes me how bright and vibrant my 30-year old comics on their old newsprint paper look compared to today's computer-generated mud on super glossy paper. I often feel like I'm looking through an old coffee filter at the world that was once crisp and inviting, even when the tone of the story was dark.
And for me, it's not just the "catfish-coloring" (beautiful term, by the way); it's the monochromatism...is that a word? Monochronasity? Monochromatoa? Anyway, the practice of using one color on a page, or in a lot of cases, the whole comic. This seemed (to me) to really take hold around the early 2000's, with titles like Daredevil would go whole issues of using only one or two colors, and not at the same time. Several pages would just be red, then a few pages would be just blue, then back to red.
Don't get me wrong. This can be done to good effect and has in the past (Frank Miller's work on Daredevil is a good example), but it's done so often now it has completely lost its potency for conveying a tone or feeling, and instead just feels like lazy coloring. "Oh, I've got to catch the 3:00 flight to fill-in-the-blank convention and I've still got 10 pages left to color that are due by tomorrow. I'll just red-wash these 5 pages because they're fight scenes, and these 5 pages in orange because they're romantic scenes (and all romance happens at sunset, right?). Done, done, and bring on the convention appearance fee!"
Anyway, back to your article. This should be published someplace. Well, in addition to here. Newsarama, CBR,somewhere with a larger (but not necessarily better than here) audience. This is good stuff.
