Change text color under images

Hi,

I am sure this is easy but I can't seem to find the answer. I would like to change the color under these images to white from black. Any guidance very much appreciated.

Thanks

The text under the images in the link above

@zato try adding to Home > Design > Custom CSS

.sqs-block-content {
    color: white;
}

You are awesome! thanks
