Painting Morning Walks

Is there a possibility that the activities or habits we do in our daily life can turn into meaningful data?
What do we encounter when this data is collected from nature with the digital method and transformed into an art practice with the traditional method?
Collecting pieces from nature is a common activity among people of all ages. In my collecting experience for the project, I realized that nature and natural pigments were the essences of art and aesthetics. As each sample from Ilm Park enters the collection, it is labeled with a corresponding number (according to the order of discovery). In a notebook, I recorded where the leaves and other pieces are coming from.
I have been going for a walk to Ilm Park in the mornings since I moved to Weimar (April 2021). During these walks, I realised that I had collected dry branches, leaves and lichen pieces, dry moss etc. that had fallen to the ground from different parts of the Park and brought them home with me. As my collection grows more and more I realised that the way they got together created a completely aesthetic image. I noticed that the combination of these parts creates quite aesthetically and holistically meaningful gatherings. I wanted to create a Digital Color Archive of my walks in the Ilm park with custom shades that belong to leaves and other objects.
+lichen and RGB colour sensor
+Method: An Arduino with a color sensor records the data and this data (variety of pigments) will be used to paint morning walks at Ilm Park. A color will be archived while walking every morning on the specific route determined in the park.

}+Black Box
A Black Box is used when scanning colors. This black box is a design with openings at some specific and certain corners that also only make sense when used together with the RGB color sensor.
