Suds N Sass samples

I received my suds n sass samples the other day....lovely colors.  I seemed to have a hard time  getting them to show up.  Is there a trick to really get these colors to pop.  I used my detrivore primer which is always amazing and they still didn't give me the intense payoff I was looking for.  Any suggestions?  The colors look so amazing.  I really loved the personal thank you note that came along with the order.  Very nice.  If anyone has some application suggestions please send them my way.  Thanks.....
