Chemical elements or compounds with yellowish white color
Aluminium(III) chloride - often described as white but samples is sometimes contaminated with iron(III) chloride giving it a light yellow color
Antimony(V) oxide - pale yellow solid
Bismuth(III) oxide - light yellow solid
Rhodium(III) oxide - lemon yellow
Cerium(IV) oxide - pale yellow-white compound
Dysprosium(III) nitrate - white to pale yellow
Holmium(III) oxide- Color depends on lighting condition. In daylight, it is tannish light yellow; Under trichromatic light, it is fiery orange red (Thanks @EdV)
Samarium(III) oxide - light yellow
Silver(I) iodide - samples can have a range of color(white to pale yellow to yellow) due to impurity and photosensitization
Selenium(IV) chloride - white to faint yellow volatile solid
Gold(III) chloride - pale yellow to yellow
Potassium Telluride - pale yellow
Thallium(III) bromide - pale yellow
Some vanadate salts are light yellow

Bromium nitrate is pale yellow but not confirmed. Silver(I) bromide and lead(II) bromide are light yellow and white cream colored respectively.
