Kurzweil Artis slider knob spares

Syntaur
1

I have a Kurzweil Artis 88 key stage piano. Two of the slider knobs are missing. They are dark grey with white indicators. I see Syntaur has sliders with red and yellow indictors (parts #7214 and #6319). Can anyone suggest a way to get the knobs with the white indicators, please?

Maybe this?

Or, just replace all the sliders in that one area with the yellow so that they look uniform.
