Computer graphics program for color scheme design????

Here is one for all you computer wizards. I like to plan my color schemes out BEFORE I start on the model's final finish. Is there a graphics design program (such as there is for plotting airfoils) that I can use to input a 3-view of a specific model (say a Thunderbird), and then play with various colors and or trim schemes until I get the effect I am looking for, for the actual model itself?
I used to sketch stuff, but I am not the artist my younger sister is, and it is too time consuming, and sometimes I cannot translate what I can visualize to paper by hand. Thanks guys.

Jake, What I did is to make a hand skeatch and scan it to word and then I can add color. It's the poor man's way but it works for me. The last FOUR planes I finnished are done this way.

JAK,
Any graphics program that supports layers (such as photoshop, Paint shop pro and a few others) will allow you to "color" so to speak, on any scanned image. Keep in mind though, that most high end graphics programs run into the hundreds to thousands of dollars.

When you can avoid the brand name "Adobe," you can save a fortune on software. A very good older version of Paint Shop Pro still is available for a free download and trial. The cost to register this share- ware version is reasonable, merely pocket change compared to Photoshop, and a real bargain if it's able to do what the user wants.

I use a graphic program call "The Gimp". It's open source and "free" and certainly comparable to Photoshop. Some say it's better. I use the Linux version (since I use Linux), but it is also available online for Windoze.

I use a program called Canvas. It's available for both Mac and PC, and cross-platforms well. You can download a 15 day trial version from http://www.deneba.com/.

You can draw plans, paint, photo edit and more. Not too expensive either.
