Slider image too dark

I noticed when I upload slider images, they appear darker. How do I remove this option and keep the images as is?

I'm in the process of changing themes for the winery. I had to switch back to the original cloriato theme. I hope you can still help me make changes to the woodpecker pro theme.

 

Hello
Paste the code given below in Custom CSS section
(Appearance -> Theme Options -> Styling Options -> Custom CSS) of your dashboard.
