Marvel has released a preview of Miracleman #1, a recolored reprint of Alan Moore's earliest Miracleman stories. Probably the most notable part of the preview is the remastered coloring. Marvel has totally redone the colors, giving the comic a significantly different work from the original Eclipse reprints.
Robot 6 provided readers with a comparison between the old and new pages, which shows the significant advances made in coloring over the last 30 years. Here's an example of the page above compared to its original.
It should be noted that Eclipse's colors aren't part of the original artwork. When reprinting Miracleman for an American audience, Eclipse colored the black and white art from the British version, which explains some of the....curious color choices in the originals. Take, for instance, Miracleman's purple face on the left, compared to the remastered version. It's clear that the Marvel colorist (who's uncredited at this time) spent a bit more time on the artwork than his Eclipse counterpart.
Marvel largely does away with a lot of the purples and yellows that Eclipse used, replacing them with white space and highlights. While this is by and large a good thing, I do think it actually hurts the comic in a few spots. Take the page below, for instance. While Marvel takes away the yellow coloring on the gunner's face and replaces it with a more realistic skin tone, it also bleaches the panel on the bottom left corner. While Eclipse's coloring gives Miracleman's powers a little bit of an effect on the page, Marvel opts for something closer to the original black and white artwork, which feels out of place in an otherwise colored page.
Largely, I think the new colors are an improvement over the originals, and I'm pretty excited to see what all the fuss is about. Interestingly, Marvel chose not to redo the lettering in the comics, which I thought was an interesting choice considering they had redone the colors.
