Stupid new requirement for photos to have clear lighting or else your post isn’t shown in search ?!

Is there a way to trick the algorithm with this? I make butterfly shadowboxes and I often use a black backdrop to display them. Sometimes the paper inside of the frame is the color black. Etsy constantly tells me I have to use a different photo or brighten it in order for my listing to show up on the search, but when I do that, it makes the picture look washed out and ugly. My photos are high-quality and very clear they are not grainy or dark, the Etsy bot just doesn’t like the color black and automatically marks it as too dark. How do I fix this issue ?
