Color has a measurable effect on humans. There's an extensive body of research on the psychological effects of color; every designer worth their salt knows this. The fields of branding and marketing use color purposefully every day as well.

Green has a soothing, calming effect on people because it's most common in our natural surroundings. For example, TV shows use "green rooms" filled with plants (and sometimes even painted green) to calm down guests before they go on stage for this very reason.

Orange, on the other hand, excites people and can elevate their heartbeat. It's a cross between red (hot-blooded, passion, rage) and yellow (energy, happiness, attention). You could say it encourages your emotions to interfere with rational thought.

So you can keep your appetite for large-scale redesigns! Just add a step to incorporate color psychology.
