I use bondi sands liquid gold at home on myself and I love it. The outcome is very natural yet good depth of colour.
I don’t know about the spray tan version but maybe contact them directly see if they can point you in the right direction
I really love Xen Tan. Used it for years and its never let me down. You don't need to buy the different percentages as it's one colour. The more you apply the darker it goes. Suits everyone's skin tone and doesn't come off scaley.
They will send you a sample if you ring them up too
