I’ve been meaning to write about comics veteran Tom Ziuko since the news broke
last year that he was ill.
Ziuko was a longtime colorist for DC. I vividly recall being struck by his muted yet vibrant work on the cover to 1986’s Legends #1, which I’m pretty sure was also one of the earliest covers to carry a colorist signature along with that of the pencil and ink artist(s) — in this case, John Byrne.

Byrne. Letters: Gaspar Saladino. Colors: Tom Ziuko. Editing: Mike Gold.
The Grand Comics Database lists over 1,500 credits for Ziuko spanning nearly 30
years of covers and interiors, from Superman to Hellblazer to Animaniacs, including color reconstruction on reprint projects for both Marvel and DC.
