Group 1 – Achromatic gray studies
When I learned on this group, I thought this was easy to create studies, because it was gray color. I didn’t have to think a lot of the value or hue.
Took about 10 minutes.
Group 2 – Shifting value (with color)
This group 2 was a little difficult than group 1 because of the value options. I had to try many times to make it perfectly.
Took about 15 minutes, because I had to double check the color.
Group 3 – Shifting hue, but not value
Group 3 was easy to create. I learned how to using two color but had the same value, then saw a difference in the middle square, to create the misconception.
Took about 10 minutes
Group 4 – Shifting hue and value
When I knew how to create the group 3, then group 4 will more easily. Just combine group 1-3 knowledge to create.
Took about 10 minutes.
Group 5 – Extra Credit
This group was difficult because I had to make sure the color of the middle squares look the same one.
This took about 20 minutes
