I have a pointillism project for school and I was wondering how you could blend 2 different colors without like actually blending the colors cuz you know its dots and stuff.

You can also use a colorless blending pencil to help blend colors without adding any further pigment. To do this, lay down a fine layer of colorless blender first and then add your lightest color. Dark colors can be difficult to blend once they stick to the paper fibers, so this base helps alleviate that issue. Smudging With Paper and Tortillons

the sculpture i am pretty sure you are talking about is the statue b. the david statue now lives in the galleria dell'accademia, florence, italy. it was made by ‎michelangelo.
