Changing text colour of single block on a page

How do I change the font colour in a single block using custom CSS? I'd like to change text from white to dark grey. I've attached an image of the page and block ID. Alternatively, is there another easier way to do this that doesn't involve coding? I'm a novice to this so the easier the better. Thanks!

@creedon Thanks for your reply. I've gone ahead and created a site-wide password, which is "yellowbrick33". Thanks in advance for your support with this.

Add the following to Design > Custom CSS.

.bright-inverse #block-add769d3ca114745534e.sqs-block-image .design-layout-poster .image-title *,
.bright-inverse #block-add769d3ca114745534e.sqs-block-image .design-layout-poster .image-subtitle * {

  color : red;
  
  }

This is for v7.1 and specific to the OP's need.

You can change the color to what you need.

Let us know how it goes.

It worked wonderfully! Thank you!

Do you by any chance know what code I can use to align the text in that same block to the left? It is centred right now and I can't figure out how to change it with the toolbar.

.image-block-poster-text-alignment-center #block-add769d3ca114745534e.sqs-block-image .design-layout-poster .image-card > * {

  text-align : unset !important;
  
  }

It worked wonderfully! Thank you again!!
