Natural Heat is a company focused in the energetic saving.
For this work, I take the colors of nature, showing fire (orange), water (cyan), air (red/hard pink) and earth (green). Then, I took the letters of the logo, and make a game of forms, to represent a nature simbol, which in this case is a leaf. The leaf was formed by triangles, a shape that means time, past, present and future.
Definitely, this logo means the company goal, taking care of nature now and in the future, going so much farder than in the past.
