I wonder, in older comics, what was the significance of coloring

There's probably not a lot of "significance" involved. Odds are it was either a printing error or something the artist thought would look good.

Easier

It was cheaper and easier.

>Bob, you ordered 5 shipments of blue ink instead of 2 blue, 2 red, and 1 yellow.
>Just print the whole book blue, idgaf...

They had a pallette of only 64 colors
the only way to get comtrast in a composition was with solid colors.

How is this panel "a composition"?

these are digital touchups of original panels, ya dummies!

still, the figures are small and more colors on each character would look so good

Money. Color is expensive.

>more colors on each character would look so good
that's my point. why using only one colour then?

mood/lighting differences

It's much faster and cheaper.

Making things stand out in an appealing and readable way. In the image you posted, it's used to make each character stand out as separate AND stand out against the background, with the dark colored ones in front of the cloud and the light-colored one in front of the sky.

If that doesn't make sense, just imagine how shitty that panel would be if colored "right". Torch would be wearing blue against a blue backdrop and the first thing that would pop out to the reader would be the Thing's skin.

>mood
I never got coloured all red because my mood changed

It was the best lighting effect they could come up with.
