Could you attach photos of the models so I can get a better idea where it will be applied?

I just posted four photos. Other photos can be found on this website: http://www.forgeworld.co.uk/The_Horus_Heresy/Legiones_Astartes/Space_Marine_Legion_Army_List/Legion_Troops/Legion_Tactical_Squad?filter_reset=1

Thank you for participating!

As a WH40k fan I am looking forward to work on this so expect some works soon.

Should the design use only the colors you mentioned?

No—it's up to you.
