I would ring round suppliers and request samples that way you will find what you like, Im an avivd young nails fan i love the colours the white is white, if i want to tone down the white and use soft i use pearl
Nail art colours are to die for but I also like ezflow for the glitters (there range is amazing)
get some samples sit down and have a play thats the only way you gonna find out which one you like to work with x
