Exchange's Buy/Sell Button Contrast

[Jordan-Sanchez]

The current button selection system on the exchange's buy, & sell buttons colors are extremely similar to the background, & offer no clear indication as to which button is selected.

A recommendation is to either highlight the selected button with a contrasting glow/ring around it, or to change the button colors to tones that stand out against the background, or to change the background.

While this isn't true on all color themes on some color themes it may be helpful to modify the tones to increase visibility of the buttons.
