Premiere Pro 2020 color dropper selects incorrect color

I am working with PNG and JPG image files in premiere as well as color mattes and text created in Premiere. I am trying to match the colors of the solids and text with colors on the PNG and JPG files. When creating a new color matte, I tried using the eyedropper selection tool to match the color matte to the image file, but the color matte always turns out darker than the color in the image file.

I've also tried matching one color matte with another one using the eyedropper tool, but for some reason the selected color is always darker than the original reference color.

See images. The rectangles are color mattes that have been colored with the dropper tool to match the circle. The end result is always darker than the original reference color. These shapes should all be the same color, but the color dropper tool seems to be picking an incorrect color. This used to work correctly but is now causing problems. Please help.
