Try
imshow(colorimage, [])
And tell us what you get for
class(colorimage)
size(colorimage)
min(colorimage(:))
max(colorimage(:))

You gave those four commands, and the response was just the literal words
size(colorimage)
??

I suggest you do what Walter asked. If you refuse (which would be strange - why deny us the ability to help you?), then try this and see what happens
imshow(uint8(colorimage));
and if that doesn't work try this:
imshow(uint8(255 * colorimage));

I would normally expect the [] range specifier of imshow() to work usefully in the two cases the above would help with.

Yeah, so would I, though it doesn't. It does scale min to 0 and max to 255 with gray scale double images, but not with color double images. I'm not sure why it doesn't work with color the same way as grayscale. I'm sure they could if they wanted to program it up that way. I'll put it on my wish list and talk to them about it.
