The syntax highlighting for mobile on Android Chrome seems to be using a different set of colours, which looks much worse on mobile browsers (true over multiple SE sites)
Here's a side by side comparison (click through for the source of the screenshots):
mobile browser desktop site on the left, mobile browser mobile site (looking worse) on the right.
More zoomed out and for larger blocks of code, syntax highlighting becomes basically useless for the mobile site. This is for VBA, but I'm sure it's an issue for other languages too. Is it possible to update the mobile site to use the latest colours?
