If you like Orange, you can try it yourself, even as a total noob.
What you'll need:
A colorator
A bleacher
300 cans of paint per color field on the garment (more on this later)
To color a garment.
Equip the colorator.
Drag the garment into the upper window.
To play with color schemes, you can place paint of various colors in each field at the bottom of the colorator interface. Doing this is free and can help you decide what you want even if you don't have the skills to actually use the colors you decide on. Note that if you have NO chance of success with a color, the colorator won't let you try (IIRC). The chance of success with each field is shown in the lower section of the colorator screen.
If all is set and you want to try it, hold your breath and pres the button!
You can use less than 300 paint per field, but if you want the best chance of success as a total noob, that's what it takes.
The previous posters have given great information already. If you don't want orange, find someone that can do the job for you. You (and the colorer) will be glad you did.
