Are there chemical elements or compounds that have a yellowish white (cream) color in their natural state?

  1. Aluminium(III) chloride - often described as white but samples is sometimes contaminated with iron(III) chloride giving it a light yellow color
  2. Antimony(V) oxide - pale yellow solid
  3. Bismuth(III) oxide - light yellow solid
  4. Rhodium(III) oxide - lemon yellow
  5. Cerium(IV) oxide - pale yellow-white compound
  6. Dysprosium(III) nitrate - white to pale yellow
  7. 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)
  8. Samarium(III) oxide - light yellow
  9. Silver(I) iodide - samples can have a range of color(white to pale yellow to yellow) due to impurity and photosensitization
  10. Selenium(IV) chloride - white to faint yellow volatile solid
  11. Gold(III) chloride - pale yellow to yellow
  12. Potassium Telluride - pale yellow
  13. Thallium(III) bromide - pale yellow
  14. 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.

    $\begingroup$ (+1) Excellent list! I have numbers 5, 8 and 11 and can confirm that the color of holmium (III) oxide depends on the illumination, as per here. $\endgroup$

  • $\begingroup$ @EdV Thank you. I am editing that information onto the answer. I was hoping for someone to confirm the list as I compiled the data from a single source. $\endgroup$ Commented Jul 5, 2020 at 12:45

    $\begingroup$ In addition to the various inorganic compounds listed above, there are countless organic compounds (and mixtures/emulsions/suspensions/etc. of organic compounds) that satisfy this criterion. Also, sulfur contamination of something that's normally white will give you something yellow. $\endgroup$ Commented Jul 5, 2020 at 18:04

Calcium hypochlorite is an example of such a yellowish white compound.

Another example would be Silver Bromide

    $\begingroup$ The only reason I can think is that your link to Ca(OCl)2 takes you to AgBr $\endgroup$

  • $\begingroup$ Thanks for that. @IanBush I had both links marked in the answer but had a mix up in alloting them. I fixed the issue. $\endgroup$ Commented Jul 5, 2020 at 11:02

    $\begingroup$ Article you link says calcium hypochlorite is white/gray. Also such questions are supposed to be closed as too broad, not answered. $\endgroup$

The reaction of any acid on a thiosulfate solution makes a precipitate of sulfur $\ce{S_8}$ which is pale yellow, nearly white.

Undyed ("natural") nylon is yellowish-white:
