What is the yellow colour and what ingredients go into seekh kebabs fat?
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).
