SPME arrow dark grey?

Question

Hi SPME Arrow users, 
 Can someone please let me know if I am using the correct "dark grey". 
 
 Is the colour of the arrow when exposed "black"? 
 I need to use: Dark Grey, Part Number:5191-5861 (all 3 phase) 
 
 There is another "grey" but when exposed it is yellowish colour. 
 
 Thank you. 
 Cheers

Hi , 
 The colored hub signifies the phase type (color of the coating). 
 
 The phase color can vary a little. When the phase is black-ish it means that there is carbon in the phase. 
 If the PN of their arrow is 5191-5861 then that&rsquo;s DVB/carbon WR/PDMS and should appear black.
