Improve transactions color scheme to avoid confusion

[MaudSimon]

Several users reported that the red color for outgoing transactions was confusing as at first glance it looks like a failed transaction from the color scheme.

One suggestion was made to use the same color for both with just up and down arrow.
(Personally I think that having a slightly different color is helpful, just not red so it's not confusing).
