Help change jquery fade-in colour

[Ggaivg]

When browsing product lists (not product pages) on my site the pictures fade in starting from white. This creates sort of a white flash when fading in. I've been looking but haven't been able to figure out; where do I change the starting colour of this fade-in effect? I'd rather have it fade in from black or pink.

 

See example on: http://www.silvrigast.se

 

Thanks

Did you tried change css background-color of this elements?

Yes, I changed the below elements. The background changed but not the flash.

 

 

#center_column div.products_block a.product_image {

background-color: red;

 

ul#product_list li div.left_block {

background: red;

 

ul#product_list li div.left_block_large {

background: red;

Try

 

.bx-viewport {

 background: black; }

 

in homeslider.css
