I am using a picture of a “Blue Sky with Clouds, and Bright Sun” coming through the clouds – as a background.
And I have text showing as the audio track is reading the text.

Problem is – I clicked something (not sure what) that made my beautiful blue sky jump to a pinkish/purple. Yuck! ….I tried to undue my mistake by using “Control Z.” I un-did my last few actions as much as I could to make my pink sky jump back to blue.

Nothing I could find could make that happen. So, I removed the Blue-Sky background altogether.

Then I inserted a new blue shy background. Guess what happened?
It also jumped to Pinkish/Purple.

Can anyone tell me what could cause this.

I admit, I have not learned to use the program to that level.
My videos can come out looking pretty good for someone who only knows the basic of video editing.

Would highly appreciate some help.  Thank You in advance.
