[BUG] 4.7.1 - The default value for a Linear Color parameter inside a Blueprint function parameter is a text field instead of a color picker and RGBA floats

For anyone wondering how to type in value in field presented in such a way, I figured an answer after a bit of testing.
You need to type in it as following:
(r=0.0,g=0.0,b=0.0,a=0.0)

Works in 4.14 for me.
