Different Clock Symbols in Top Design for PSOC 4

HI, 

I've noticed that the clocks have different symbols in the Top Design of PSoC Creator for PSoC 4 CY8C4125PVI482.

I'd like to mention that the clock on the left (in image, sorry i do not know how to embed an image, apologies) is an Existing clock and the Clock on the left is a NEW clock - this option is available when configuring the clock. 

Is that why the colour of the wave inside is GREEN and WHITE, respectively?
