Visual identity

Investing money in sports bets can be a dangerous activity. With JUSTWIN, I sought to bring a more positive image by breaking down the barriers of danger. For that we choose the blue, a color related to dreams and serenity. We use yellow to highlight the point to have a community, in which everyone can play and challenge friends. Green symbolizes boths characteristics at once.

Finally, as JUSTWIN allows to conduct sports bets without risks, without danger, the white is predominant to bring out a sense of innocence very important for the user in this kind of situation.
