What colors in logos evoke associations with environmental cleanliness and nature? I've noticed that many brands that focus on ecology and sustainability use certain colors. I think it's important to know what shades and combinations best convey the idea of connection to nature. Perhaps there are some general principles or examples of successful logos that use these colors?

This is a very interesting question. When we talk about the process of logo design, it is important to keep in mind that colors play a huge role in the perception of the brand. For ecological brands, green and blue tones are the most important. Green, especially in lighter and more muted shades, is associated with nature, freshness and the notion of sustainability and care for the planet. Blue evokes associations with cleanliness and water, which is also important for eco-friendly brands. Of course, other colors can also be used, such as brown or beige, which are associated with earth, but are used less frequently because their perception may not be as vibrant. The key point is not only the choice of color, but also its hue: colors that are too bright or too saturated can disrupt the perception of the idea of sustainability.

I think green and blue are associated with nature, but the overall concept and the target audience are also important.
