Does anyone know if this is coloustrum ?

coloustrum is generally a thicker yellow substances secreted from the nipples as an antibody for the suckling child. However you may want to make sure its not lymph fluids. if you are using a suction device too hard it will draw out lymphatic fluids from the ducts, if you see blood mixed with this yellowish fluid, chances are it is lymphatic fluid. if through suction, it turns white and milky, then yes it was coloustrum.

if it is lymph fluid, do not use suction so high and not for more than 15 min a time, you need to let the area rest
