Need changes in week view

[ravindra1191]

This is my current problem:

I need to change in week view, Like I need Monday on the very first of view and rest as continuos. I could not able to do it through the library and also can't able to find any Questions regarding this. Also, need to change in the text whether the default is coming with three characters and I need only a single character.

Apart from that I also need to change the color of the whole week's view. text color is fine but I need to change the view's color.

I'm adding an image below exactly what I want.

Like this below photo:
