Crayons of the Mountains

The Crayons of the Mountains -the new and second project after The Crayons of the Seas- create an educational experience centered on 12 crayons featuring colours taken from actual satellite images of the Earth's mountains. The vibrant hues of the Earth are a springboard for children and adults to learn about and experience the wonders of nature, to learn where on Earth each colour can be found and the story behind their distinctive hues.

The crayon making artisans, after many trials and errors, realized the colors of the oceans captured in the satellite photos in each crayon one by one. The numbers printed in each crayon is the longitude latitude of the exact place on earth that the color was taken from.

The 12 colors of the crayons are made from these 12 places in the world:

1. Mt. Everest / Chomolungma / Sagarmāthā, Nepal and China
2. Guiana Highlands (Auyan-Tepui), Bolivarian Republic of Venezuela

3. Fagradalsfjall, Iceland
4. Mt. Taranaki, New Zealand
5. The Richat Structure, Mauritania
6. Hunga Tonga-Hunga Haʻapai, Kingdom of Tonga
7. Uluru / Ayers Rock, Australia
8. Mt. Fuji, Japan
9. Machu Picchu, Republic of Peru
10. Rainbow Mountain (Mt. Vinicunca), Republic of Peru
11. Shirakami Sanchi mountain range, Japan
12. Kīlauea, Hawaii
