Modifying Vendor Panel In Multivendor

[size=5][color=#000000][font=Tahoma]Hello everyone,[/font][/color]



[color=#000000][font=Tahoma]We want to implement modifications in the vendor administration panel like changing the default blue color in the header.



But we don't want to customize the default css files and would like to know whether it is possible using 'My Changes' addon in v4?
