It's an infra-red telescope. It will image from orangish to IR, no yellow, no green, blue or violet light. It's mirrors are gold-plated, so the visual images are not going to be the glorious full-spectrum ones we got from the Hubble. This is what you will be seeing:

Wonder where the blue in the infra-red images came from? Also, resolution is lowers (though of course the Webb is much larger than Hubble) due to being in the IR end of the spectrum.
