I didn't know arsenic could also be used to make yellow pigments.

There is a famous arsenic green pigment, that was used in inks, and to color wallpaper. the arsenic ink would slowly dry out, and fall as dust, and the cleaning a room with arsenic green wall paper would be toxic!

Uranium salts make a beautiful yellow, at least in glass. there are some samples in the Corning glass museum, and some old feista ware dishes used uranium in the glazes.

Its not enriched uranium, so the radio activity level is very low.. but still measurable.
It is a very brillent yellow shade.

(there is also a sci-fi short story about an alien world, and famous potters, who make use of uranium for glazing some pottery.)
