Geore Stubbs used oils, pine resin, and beeswax in his paintings.
To show a sign of respect to the modern humans (or the Cro-Magnons) who came across them(:
Experts believe the purpose of cave paintings was likely multifaceted, serving as a form of communication, spiritual or religious expression, and a means of documenting the environment and animals. Some theories suggest they were used in hunting rituals or to convey knowledge about animal behavior. Additionally, these artworks may have played a role in social cohesion, helping to strengthen community bonds among early humans. Overall, cave paintings reflect the complex cultural and cognitive development of prehistoric societies.

It is not known precisely what cave painting were used for, but most agree that the paintings were done as a kind of religious ritual. The cave painters were depicting various animals in order to reach the animals' spirits and placate them, thus hoping to insure a safe and bountiful hunt.
Prehistoric men used natural materials like charcoal and earth pigments to draw on cave walls. They depicted animals, handprints, and abstract symbols in caves like Lascaux and Altamira. These cave paintings offer insight into the life and beliefs of early humans.

they used the cave walls for their cave paintings because if they didn't use the walls and they used nother flat surface we wouldn't know that there were paintings because they would be dust, so they used walls because they knew that other people like us would find the paintings and that we could find out what they were for and why.?1
ochre rocks were used to paint on walls
What you mean by inventing colors is not clear. Color is part of the natural world. Prehistoric humans did invent the use of natural materials to produce the color pigments they used to create and color paintings and decorated objects. Ochre is a family of pigments made from natural materials found in the earth. Ochres come in several colors including red, yellow, purple and several shades of brown. Different materials can be treated with heat to create a wider spectrum of color.Ochres were used extensively in prehistory to create cave paintings and those early masterpieces can still be seen in all their glory tens of thousands of years later. Early humans invented the materials they used to create those paintings. Deposits of ochres have been found in caves and archeological sites all over the world. Ochres were extensively manufactured and extensively used not only in cave paintings but were also used to decorate bodies, hair, animal skins, the deceased when they were buried, tombs, and other types of painted art apart from the cave paintings.From the prehistoric discovery of ochres to decorate and create art to the high tech pigments used today, every stage of humanity has added new pigments and source materials to create new colors of both paints and dyes.
Well, there are many ideas of why prehistoric humans might have made cave paintings, but nobody real knows why. Some reasons are because of decorations, capturing "magical powers", to honor the 'spirits', or used for ceremonies. Also, scientists think they were used for ceremonies because scientists sang in places with cave paintings and places without cave paintings and the places with cave paintings sounded louder. In addition, cave paintings weren't just found when you enter a cave, but they were found deep in a caves in many different rooms. Also, the cave paintings weren't only found down were people could reach, but instead very high on ceilings and walls, too. Scientists believe that prehistoric people used scaffolding to reach those places.
Archaeologists still want to know why these paintings were made. :P
