Visual Studio Formatting -- Change Method Color
For Visual Studio 2010
Tools > Options
Environment > Fonts and Colors
Change "User Types"
You can do this with an extension: SemanticColorizer is what I use.
Tools -> Extensions and Updates -> Online -> Search for SemanticColorizer
It allows you to modify the colors of methods, static functions, constants, member variables, and just about anything else you can think of.
In VS 2019 go to Tools - Options - Text Editor - C# - Advanced - Editor Color Scheme and change it to Visual Studio 2019. Method names are now colored and everything has little bit better colors.
