We need a unique and noticeable color. PURPLE could be good, but a fresh LIMEGREEN could be nice as well.
Yes you have right. With something expensive, unique, noble, associate colors: purple, gold and black.
logo should be clear and simple. consisting of a small number of colors, good-looking in different sizes (and very small) and in grayscale.
In our marketing activities we should focus on the "smart" theme. This makes smartcoin special and in this way smartcoin is being different to other altcoins. We need long lasting attention, from miners, investors and user. A large part of the value is the brand awareness of a coin.
