During daily walks I register, collect and document everything for new works. For more than a year now I have been recording all types of yellow flowers on color coding that I encounter during the walks. Butterflies mainly see and focus on the color yellow. One of the reasons is that most flowers with a lot of nectar are colored yellow. With the focus on the color yellow, I do not want to focus on the taxonomic registration of the plants, but rather be guided by the sensory experience of walking. The colors are therefore not recorded on the plant species but only on color.
