Blue is the my favorite color specifically because it is consistently beautiful with multiple shades.
I like blue as well the pigments are very beautiful but I also love yellow it is so bright.
A close second of mine is pink also. It has a lovely name that is identical to its flower counterpart.  
What other colors is close to pink on the color spectrum?
I would say it's closest to red, maybe even being a lighter shade of red. 
Do you wear pink alot of is blue more of your go to color?
I would have to admit that I do wear pink a lot more. I simply own more pink apparel. I feel more innocent when I wear it. 
I am more of a pink and red girl as well, being they are close in shades that may be why I am always picking those 2 colors out.
