Yellow is instinctively a high visibility warning sign to our minds, second only to red on the warning scale, yet brighter so more visible in the night or dark spaces. That why the most color of warning tape is 'bumblebee colors' (yellow and black), that is why Hi Visibility jackets for construction workers are bright yellow or acid green (i.e green with a high yellow content) and nearly all hardware used in and around places like construction sites are bright yellow.
As for what safety function it serves, the preservation and identification of the multimeter in the first place is a pretty big one. Leaving it somewhere it should not be (car engine, electrical substation, demolition plant) is a hazard in itself when you factor in that these are £400 a piece, professional pieces of equipment used in pretty much the most hazardous situations... and not your £20 model from the store.
