Hi. My friend and i r working on an iOS application referred to as a communication/board for tattoo artists/designers and enthusiasts. Before we begin too much work on it we have started working on art styles, color palettes and themes that we would like to stick with. From my initial vision i started with purple and white. We are mainly using uikit so two colors are not going to be sufficient as there would be many elements. With the two colors purple and white kept in mind what other colors would fit in to our theme? White being used for text and purple for background and solid color elements atm. Also if you think scrapping purple and white all together for a different palette would be a good idea please tell me.
