Square Block formating

Hello,

how can I get the colored squares bigger in height and the h3-tag wight, instead of black - and inside the square?

Thank you,
Oli

I added to your custom.css

.example-colors .swatch-item h3{
  color:#ffffff;
  font-size:30px;
}
.example-colors .swatch-item {
  min-height:150px;
}

Very good.
Thank you very much - that was exactly, what I wanted.
You are awesome.
