Brown caulk worked just fine no issues

Using old-school white latex caulk on outdoor trim leaves a lot to be desired, namely it shrinks and splits where you need it to seal. Enter DAP Dynaflex. This fills BIG cracks, a bit over 1/4" just made it yawn and say, "can you please give me a challenge?" Flows and applies easily with a caulk gun, and if the label can be believed, stays pliant and won't fail. Time will tell, but so far so good.

Let’s get to the point. Colour as described. Simple use. Does the job. What more do you need?!

This color, like other DAP colors, was a good match to our wood floor, which was the reason I chose this color of calk. Cure time was not excessive and adhesion was good. I've had good luck with DAP colors in the past and this was no different.
