Chapters 105, 112, 116, 126, 133, and 138 had one color page each

Chapter 126 was also published in Weekly Shonen Sunday issue 9, 2022 which had MAO on the cover.

Chapter 133 was published in Weekly Shonen Sunday issue 16, 2022 which was a group cover to celebrate the magazine's 63rd anniversary

Chapter 124 and 144 each had three color pages which included doublespreads

P.S. Bonus full drawing of Mao from the group cover:

The cover for Weekly Shonen Sunday issue 45, 2022 (ch.158 was published here) featured Mao with Lum from Rumiko's first serialized work Urusei Yatsura in honor of the latter's new anime adaptation

One color page each for Chapters 147, 152, 155, 159, 166, 171, 177, 184, 188, and 190

Weekly Shonen Sunday issue 16, 2023 was a group cover to celebrate the magazine's 64th anniversary (ch.179 was published in this issue)

MAO was also on the cover of Weekly Shonen Sunday issue 39, 2023 (ch.197 was published here) in honor of the 45th anniversary of Rumiko's career – and thus Urusei Yatsura's 45th anniversary

VIZ began simulpubbing MAO with chapter 186, and as a result of that there's versions of the color pages with less text and ads after this point

Chapters 63, 66, 72, 76, 80, 90, and 91 had one color page each

Chapter 85 had three color pages and was published in Weekly Shonen Sunday issue 16, 2021 which was a group cover to celebrate the magazine's 62nd anniversary

Chapters 28, 32, 37, and 46 had one color page each

Chapter 32 was also published in Weekly Shonen Sunday issue 8, 2020 which had MAO on the cover

Weekly Shonen Sunday issue 16, 2020 was a group cover to celebrate the magazine's 61st anniversary (chapter 39 was published in this issue) See Mao with a bowtie? :)

Chapters 43, 53, and 57 had three color pages each – none of them were actual spreads like in the previous post but I made them a spread because the background colors between panels connect (in the volume version these background colors were removed)
