Colours faded when exported in Animate 2020

[TMcFlurry]

Hi there I'm hoping someone can help me. I animated just under 2000 frames in Adobe Animate (2020) and for some of those frames I used the Classic Brush Tool on 70 or 90% opacity. In the program the colours looked fine but after exporting it as a PNG sequence (in order to have a transparent stage) the colours are much greyer. I've attached two images to show the difference. How should I export so that I can have a transparent background and the correct colours? Also I don't know if this matters but I imported a video to animate over top of, then deleted that layer so the program didn't export the video too. I don't 

 know if that's affecting anything? Any feedback is helpful. Thanks!

Hi mate,

If they are all on the same layer, you will have to manually re-colour them with the Paint Bucket, using solid colours of your choice.

If they are each on its own layer, you can use Edit Multiple Frames, unlock layers one by one, select everything and apply a solid colour with 100% alpha.
