Blender rendering in black and white?

Hey, got a small problem here when it came to rendering my scene…

When I hit render, the preview window showed the images in full color, but when the animation is done, I checked the output folder and its in black and white! is there something I left unchecked or something?

anyone? please, I need to fix this if i want to continue and finish this project!

version of blender? what format do you render to? under the format there is a “BW/RGB/RGBA” switch, check that…

I am currently using blender version 2.58, i rendered out the animation as jpegs and splice them together, just incaase blender decides to crash in the midddle of the night, i can start where the last frame was rendered.
