David Fisher, The Complete Photo Guide to Soap Making (Creative Publishing International, 2018), p. 20: dyes "give a full range of hues—from subtle to bright and bold", but "can bleed between layers or swirls of soap, especially in melt-and-pour soap. Some are not stable in cold process soap, so test them first"; oxides "are very stable and strong in soap". Natural colours, pp. 82–84. In an infused oil: "Annatto: yellow-orange"; "Alkanet: light to deep purple, depending on the amount used"; "Paprika: orange-peach". In the lye solution: "Indigo: light to deep blue"; "Madder root: pinkish-red"; "Rose clay: deep rose pink".

Heidi Corley Barto, The Natural Soap Chef (Ulysses Press, 2012), chapter 5: "When adding lye to a purée, I always use an ice bath"; the purée is the lye liquid, for 566 g of oils: 215 g of chilled puréed carrots (38 % of the oils), 150 g of canned pumpkin with 65 g of water (26.5 %), 215 g of a cucumber and coconut milk purée (150 g cucumber to 100 g coconut milk).
