After a few recent questions I think I'm finally getting a better idea between Yellow & Blue Paloverde. This I "believe" is a yellow. The leaves have more gaps, hence the common name "little leaf". The leaves seems to alternate whereas the blue don't. The leaves on the blue slant out more too. Also good to note is these yellow paloverdes all have their leaves as of mid April. The blues are barely getting their leaves. You'd need a magnifying glass to see them!
