The image is a slide from a presentation on the concept of cycladic art. It is titled "Colour in Cycladic art" and is written in black text on a beige background. The slide is divided into two sections. 

The first section explains that cycladic craftsmen made extensive use of colours in their creations. It explains that several marble bowls have their interior surface painted red (no. 66 in blue pigments) and that some of them have been found in the bottom of deep vessels. The second section discusses the different types of pigments used in the art, such as red, orange, and green. The text also mentions that black occurs rarely and may have been the result of oxidation of another type of pigment.
