I'd think about every mod you do... how hard will it be to sell the car afterwards with these mods you are talking about, or how hard will it be to change the car back to stock.

If you go for pink for everything, say dash lights, brake calipers etc etc, then you are basically limiting your future sale to a smaller target audience, say females in your current age demographic, or gay males...

I would just get some sticker work for the car (maybe even go get a sticker wrap done) like a rally car, in STI pink, make it stand out a bit...
