Fading Directional Light between two colors

Okay, So I setup a variation of colors for my Directional Light (SUN) from Orange at morning to white at noon-ish. Problem is, its like a switch. It just goes straight from orange to white and it looks horrible. Im not sure how to blend the two colors over time. I have them setup for an event tick. I will post some pictures.

These are my settings. The pictures I took for the in-game results are too large to upload, if you really want to see them i can post them to photobucket or something. But if you have any suggestions please let me know.

Figured it out. Heres a picture of some nodes I added.

(By the way this is all in my Levels Blueprint)
