I created custom colors for banners within photoshop, have saved/exported them as pngs, and when I place the files into InDesign the colors do not match at all. Interestingly enough, it only struggles matching shades of vibrant blue. I have checked all of my color settings in both programs and they match up. Files are saved as CMYK files and placed in CMYK docs. Below are screencaps of what the file looks like in Photoshop vs what shows up in InDesign, as you can see they are VERY different and yet are the exact same file. Help?? Thank you!!
Intended color in photoshop
Color that shows up in InDesign
The difference is caused by the fact that when you display a page in InDesign and there is any transparency, as there appears to be in the image that you show (by virtue of the transparency checkerboard background in Photoshop), you actually see how the page would look in the current CMYK output space.
You would see the same thing if you re-open the image in Photoshop and invoked View=>Proof Colors, a CMYK version of your bright blue which is obviously not bright blue since no CMYK printer has the gamut to reproduce that color.
Bottom line is that everything is as designed and expected.

...Files are saved as CMYK files and placed in CMYK docs.
PNGs cannot be saved as CMYK.
