Painting handrails on KATO UP SD90/43MAC

I was wondering if anyone here put together a UP model of this loco? I want to paint the grab irons yellow that were attached to the yellow part of the body. I left the grab irons gray that attached to the gray parts, but I can’t seem to figure out exactly what color the yellow is. Maybe someone can help me here. I pulled out pics of this loco and they are yellow. I want to match the color exactly so they don’t look crapy.
