Like we said in the other thread, you're pretty much limited to the shock mfgr's available colors.
The fork is not made by TREK, it's an SR Suntour, and while it's still in production, it's only available in black.

If the forks on your 5-year old bike wore out / broke, then you will have to replace them. There are a lot of much nicer 700c hybrid forks than the one spec'ed as OE on your bike. They just won't match.

If it's that much of an issue to match the colorway, then get a replacement fork and have it custom painted to match.
Or replace your current bike with one that has a working, color-matched fork.

You could also have your old fork rebuilt, but being that it's a basic coil-spring unit with a lockout/damper cartridge in one leg, the cost of service might exceed cost of replacement.
