Overview

Save Big on Coursera Plus. 7,000+ courses at $160 off. Limited Time Only!
Learn how to prevent or minimize color bleed in your SketchUp projects. Learn about the basics of color, lighting, and reflectance so that you can control when color bleed occurs.

What are the causes of color bleed and how can it be prevented, minimized, or controlled in SketchUp? Brian Bradley shows you how in this course. First, Brian discusses what color bleed is and why it occurs. Then, he dives into measures you can take to control color bleed and produce physically accurate color. He explains how white balance, saturation, light, and geometry impact color bleed. He also demonstrates how you can work tools to contain or limit color bleed.
