There were color cameras during this period however they were not the best. However now in the digital age they are able to get some of that film and make pictures look brand new. Below is one such link.
The website theatlantic.com has a great assortment of WWII HD color photos. The pictures they have on their site are the best I have ever seen. They are such fine detail you would think they were taken last week.
I have also attached a link for ww2incolor.com they have over 500 color photos of WWII. They are not near the quality of the first website however every time I sit around and wonder how it would have look those types of images come to mind.
If you have any such website you would like to suggest please let me know so we can get it posted for others to see.
Youtube is a great site to find WWII color videos. Watch the video of Midway in color below you will see what I mean.
