Considering a change- thoughts/suggestions?

I am considering dyeing my hair! I’ve never put dye in my hair at all. I am blonde, and I worry about putting darker colors in my hair... is it hard to get your natural color back once you start dyeing it? How expensive is it? Any thoughts on adding dark colors to blonde hair? Specifically like a mulled wine/burgundy shade :)

Above are the type of colors/styles I am considering

Here’s a picture of what my hair currently looks like

Any stories/advice would be appreciated!! 💗

**UPDATE**

I did it!! A bit different than I originally posted, but I am absolutely in love with the results!!! Never figured I’d be a redhead, but I love it!! 😍
