Boots color & graphic pattern?

Does anyone know the reason of the color and the graphic on mountaineering boots? ( I mean the double layer type's boots)
I realize the color is much brighter and more contrast than normal hiking boots. Or is there any color when you wear those boots, you will feel more secure? As I know mostly the color is based on black, and then add some orange, yellow, or blue.
Sorry, forget to mention, I'm designing the boots.

1. Brightness. This allow climbers to see their feet during climbing, especially during early morning for alpine starts and late at night.
2. Contrast. Black rubber provides climbers contrast so they can see the crampons and ice/snow, and or where shoes contact with the rock when climbing without crampons.
3. Graphic. This is branding decision rather than climbing decision.

I stayed at a Holiday Inn last night.

You're over thinking it bro.

I don't get it. What are you asking? You want to customize the color of your boots????

Sorry, I'm designing the boots. I forgot to mention.
