What is the yellow colour and what ingredients go into seekh kebabs fat? When grilling seekh kebab fat drips I notice it's yellow colour.  If you grill plain mince or meat it's usually white colour so it must mean some ingredients are getting imparted into the seekh kebabs fat to give it that colour. I really like the taste of look of this fat.

What is giving the fat this yellow colour and what typical ingredients do you think are going into the fat since it doesnt seem to be pure fat?

I think typical ingredients for seekh kebab are garlic, ginger, onion, coriander, cumin, powdered pepper.
Common sources of fat-soluble yellow colours are curcuma (curcumin as colorant, tends to give an almost fluorescent yellow), and chilli peppers (lycopene, tends more towards the orange in higher concentrations). But a lot of other carotene-containing items can give a yellow to orange colour (cumin among them, but it's less known as a colorant).
