I’ve gotten the question where did red withdrawals from several users so I thought I’d explain the reasoning behind removing them.
The reasoning withdrawals are black and deposits green is that items displayed in red are meant to be warnings to the user that something is going wrong. When you exceed your budget amount the bar is red. Whenever your account is over the limit or falls below the minimum balance the running balance and overall balance is displayed in red. Red is used sparingly, and as a warning. If you see red then something needs correcting.
I picked green for deposits because users typically have fewer deposits than withdrawals so the green does stick out among the black withdrawals if you are scrolling your transaction log looking for deposits.
