I just thought I would post this image because I find it very striking, the hot coloured lichen in the stripes interest me the most, even though they aren't miles away from the warmness of the brown bark. I would like to take these colours into the weave room, but use them against a cold coloured background instead.
Another great image found in this book is this one:
This is a very interesting looking lichen, called map lichen, found in Glacier National Park, USA.
Whilst looking for imagery of lichens, I have found out some interesting facts about lichen too. One of the most intriguing facts about lichen was that they are very sensitive to air pollution, in particular sulphur dioxide, and is used by scientists to indicate polluted areas. Bushy lichens will need to have clear air to grow, leafy lichens can survive a small amount of air pollution and crusty lichens can survive with more polluted air. If there is a large amount of sulphur dioxide in an area, no lichen will grow.
I think this is an interesting thing to bear in mind, how the environment defines the type of lichen, in colour and texture. I could consider how environmental factors could change my work, such as hot/cold, (maybe trying to find some heat reactive dyes or pigments to experiement with) light/dark, (glow in the dark fibres etc?) dry/wet (colours that change when wet?) or even by using something that changes colour/texture over time? These are all interesting things to bear in mind when I am producing my collection of weave samples.
