Color is an interesting thing It's definitely easy to go overboard, and other times you just need it to be the boldest thing in the picture. I'm still debating as to whether or not I like the edits I did on this picture:
In the case of this picture, I think the color is necessary, because otherwise it would be kind of a boring picture; the color helps make the sky seem HUGE. Before I edited this picture, it was just "meh"
This picture, I think, benefits even more from changing the colors.
For comparison, here it is unedited
The color enhancement made any foreground detail go away (which is what I was going for, because some of those buildings are ugly in comparison to the sunset). The color adjustments made an already beautiful sunset simply amazing.
Yes, these are the same sky on different days. Kinda interesting to get almost identical shots of a morning and evening sky.
Some more fun before/ afters
