What is the man doing?

W: Hi, Mark, I didn’t know you could paint.
M: Well, I’m just learning. It’s for my studio art one of one class.
W: It’s pretty good for a beginner.
M: Oh thanks, Judy. The instructor really liked my schedules, but she hasn’t seen my painting yet.
W: En, there seems to be something wrong with it though.
M: Yeah, I know what you mean. It doesn’t look like to me either.
W: I think I know, look here at the sky, it just seems to filled in with other colors of paining.
M: What do you mean? Everyone knows the sky is blue.
W: Well, that depends. Sometime it is and sometime it isn’t, as sunset can be full of reds and purples. Well, even now, look at now Mark, what do you see?
M: It looks blue to me.
W: Look again. Do you see a kind of tallish color?
M: Oh yeah, I see what you mean.
W: By adding some tan to your sky, I think you’ll get more actual picture, and the color will look more natural.
M: I think I’ll try that. Gee, how do you get to know so much about paining? Have you taken a lot of courses?
W: No, actually. But my father is an artist.
M: A professional artist?
W: Oh yeah. He shows his staff in lots of exhibits, everything is when we were kids; he always talks to us about his work.
M: I wish we could talk some more Judy. How about going for a cup of coffee? I’m ready for a break.
W: I’d love to, but I have to study for a history exam. In fact, I was just on my way to the study group, and I think I am already late. Maybe tomorrow?
M: Great, I’ll meet you at the students’ center after my class. A little after three, OK?
W: Sounds good. Get around now.
M: Bye, Judy.
