Ah - the dilemmas of new and old hair...
Personally I can totally sympathise as I've dyed my hair since 14 - every colour and shape you can imagine.
Now as an old woman (ok for old see responsible and working in an office) I keep the experimenting for different shades of red, black and blonde - but to be honest I once cut out the colouring and HATED the colour I saw - that was because it reminded me why 'brown' didn't suit my personality.
But I had to try to know. I say get it cut - live with it for a few days and if you hate it GO WILD IN THE AISLES...
