Brown temporary hair colour (Biggleswade SG18)

Shampoo-in hair colour bought online that is stated to cover grey and to gradually wash out. 250 ml bottle, only a tiny sample used. No box, just the bottle. To be shampooed in on dry hair, left 10-30 minutes depending how strong you want the colour to be, then rinsed out.
The colour is named Honey Brown, but I did a strand test first and it came out far darker than expected after 10 minutes -- a dark brown with hints of burgundy! Likely to be fine for someone with darker brown hair wanting to cover a few greys, but I'm looking for a lighter colour.
Ingredients are Aqua, Acrylates/C10-30 Alkyl Acrylate Crosspolymer, CI 77499 / Iron oxides, Propylene Glycol, AMP-Acrylates/Allyl Methacrylate Copolymer, Cetearyl Alcohol, Argania Spinosa Kernel Oil, p-Phenylenediamine. As one of the ingredients can cause allergies, a patch test 48 hours before colouring, as will all hair colours, is recommended to be safe.
Collection only from Biggleswade.
