If you want to make your artificial palm fronds look more realistic we suggest lightly spraying the tips with a light yellow. This spray paint can be purchased at Lowe's and is the Valspar brand. This mimics the natural browning of the leaves. This will add more of a pop to the palm fronds and to your artificial palm trees. The highlight will add a more realistic look to your fake palm tree. Choose a calm sunny day and leave the palm fronds in your tree which will make the paint dry faster.
