Thank you all for your efforts ! The logo is growing and it is now time for other guidelines for everybody:
1) the graphic should be predominat on word (like logo #3 and #1) or at least strongly integrated (like logo #2)
2) please use possibly both blue (like the sky and the sea) and green (like nature during spring). Additional other colors are allowed : you decide (orange, yellow ecc) !
3) Use vivid colors, we want something impressive, not something that looks flat (like #6 and #1)!
3) The graphic should express both "danger" and "pollution" concepts verse "protection" and "safety". A shield could be an example, but it is overused and often improperly used (links to the concept of aggression).
Example: two hands that tenderly keep and that sustain a man or a building protects from danger (that could be represented below): The hands (LABORAD) takes you away from danger) while a hand rapresented like a punch is too aggressive, please do not use it !
A bubble or a stylized house around you or around a family while the danger is represented outside is another example of danger and protection represented together.
A peaceful natural landscape o simply a leaf or a tree represent nature. If you put a yellow helmet on it you represents shielding and protection, but also safety in workplaces, add the danger....
These are guidelines and examples to let you understand what we need, not requests... PLEASE MAKE USE OF YOUR UNIQUE AND SPECIAL CREATIVITY !
4) pollution is not only the radioactive symbol: please use your creativity ! A cloud of dust could indicate pollution, a wave could indicate a "radiation" (electromagnetic, radioactive or optical...) a stylized industry building is potential danger but is also a workplace and our target costumer...
