Shade Progression (Black to Tint Blue)

This was a picture I took on some interesting English textbook from middle school. It seems like a wild book of tint blue and black, but the progression starts in the middle bottom to spread out to the top.

Tint Progression (White to Green)

This was a simple picture I found. The progression changes from White at the right to turning Green when looking left.

Two-color progression (Dark Pink to Tint Pink)

This was a really hard part to find any Two-color progression and I chose this. The Cherry Blossoms has the progression change from dark pink at the middle of some flowers into turning tint pink when spreading out from the middle.
