The flat pierced seat tube made me think it was old school , then I checked the rear dropouts & got totally lost....it must be newer than the 1986 24 inch GT we have , Matt is still messing around with the colour scheme on that.....
I found that a simple mix of Blue , Black & Chrome combo sits nice on the Satan Ana 26 inch GT's

Along with some little yellow Bottema stickers for the supercross forks + a yellow label comp III to compliment the yellow in the GT stickers....
FWIW:
Try to match up your colours mix as close as (financially) possible to each other , the gold & black are a nice mix but the shades of blue coloured components on it atm really wander all over the spectrum & throw out any colour combo or asthetic balance you are trying to mix in , right out of whack.
The primer grey handle bars won't help much either when you are mocking up a bike & trying to get the look you are after.
I am by no means a magnificent Artiste' , but as an Electrician your life depends on really knowing your colours , so I have paid a _lot_ of attention to colour & always look for variations in it , those variations are
a good indicator of pending trouble etc.
