I found this model on printables from Ender005

To make the Inspiration System a bit easier for a DM, Brian Schrader came up with this idea:

Here's a breakdown of the categories:

Backstory (Yellow) - A player can earn a backstory point if they roleplay a situation that is heavily influenced by, or gives some indirect insight into, their character's background. This can be something like telling a personal story while the party sits around a campfire or during a religious confession.

Flaw (Purple) - A player can earn a flaw point for roleplaying a possibly contentious character flaw. Maybe their character is too distrustful and sabotages the mission, or because of their thieving background, they hide crucial information from the rest of the party.

Combat (Red) - A player can earn a combat point for flashy or awesome combat moves, clever planning, or roleplaying out spectacular maneuvers.

Fellowship (Green) - A player can earn a fellowship point for using their skills or character traits to inspire or build trust with the other characters in the party. A character's rousing, fireside speech, or brave leap into the path of an oncoming Witch Bolt to protect another party member are good examples.

Ingenuity (Blue) - A player can earn an ingenuity point similarly to a combat point. This rewards slick persuasion, lurking stealth moves, or clever planning outside of combat.

You can also buy it directly from Ender005:
