I repeated the experiment with different colors and and a new medium. This time I used the Euglena from the beaker glass. With altogether five colors I wanted to create more | I repeated the experiment with different colors and and a new medium. This time I used the Euglena from the beaker glass.

After one and a half hour of illumination I reached a more satisfying result then before. On the bottom there were three separeted stripes clearly visible. As I knew Euglena is not able to see red light and maybe also orange because it is a mixture of yellow and red. All the other colors - yellow, green and blue - seem to be transparent and light enough to be a good concentration point. Between those stripes were thin parts where the colors overlapped and made a darker shade. Those areas are clear and not (or only less) besieged by the organisms. | After one and a half hour of illumination I reached a more satisfying result then before.
