Wappos theme, need to change colors

I am using the Wappos theme but I wanted to change from a blue-based color scheme to a purple-based one. I edited the stylesheet and replaced the color:# ______ with the ones I wanted. When I load the page, I get a split second of the purple theme (that I want) before it changes to the blue theme (which I don’t want) and stays blue. I cannot for the life of me figure out why it’s switching back to the blue.

I am incredibly new to this and have no real HTML knowledge, so if I’m missing something obvious, please forgive me.

Style.css:

@charset "utf-8";
