Unit 3 Lesson 2 bubbles

From the 2nd bubble on I don’t know how to do things like pick the matching color, I’ve tried getting close with the color swatch thing but it doesn’t look the same. Is there anyplace I can go to get hints or help on how to get through this. The students I teach are all mulit-lingual learners and this is a big stretch so not being able to help them is frustrating. I’m new to this this year…teaching it as an after school class.

I had my students copy the image and paste it into a photo editing software. From there they used the eyedropper tool to get the rgb values.
