Early on in Clair Obscur: Expedition 33, you’ll start to collect a variety of materials called Tints. These are consumable items you will use to upgrade your characters in various ways, such as leveling up your weapons and increasing your Lumina points.

Ben Starr and Jennifer English let their auditions do the talking for them.
While the descriptions on these items suggest how to use them, it isn’t clear what you need to do. If you’re holding onto a pile of Chroma Catalyst
and Colour of Lumina and wondering how to use them to upgrade your weapons and increase your characters’ Lumina, we’ve got all the details.
How To Upgrade Weapons
To upgrade your weapons, you’ll need to talk to a specific vendor called The Curator. Once you’ve unlocked him, which will happen through the main story, you’ll find The Curator inside a cave at your camp, which is accessible at any time from the overworld.
Enter your camp, then turn towards the cliff and look to the left to find the opening to the cave. You can also walk to the edge of the cliff and follow the path around to the left to find a second opening to the cave. Talk to the Curator, then select [Upgrade Weapon].
Weapons can be upgraded from Level 1 to Level 3 using Chroma Catalyst. It costs one catalyst to upgrade a weapon to Level 2 and two to upgrade it to Level 3. Each time you upgrade a weapon, its Attack Power and Attribute Scaling increase, improving its raw damage and the amount of additional damage it does based on the level of your combat skill levels. After Level 3, you’ll need rarer items to upgrade your weapons.
Increasing Your Characters’ Lumina Points With Colour Of Lumina
Similar to weapon upgrading, you can spend your Colour of Lumina by visiting the Curator in your camp. Enter the cave to the left of the cliff and speak to the Curator, then choose the [Upgrade Expedition resources] option.
Each Colour Of Lumina you spend will increase a character’s available Lumina Points by one. The more Lumina Points a character has, the more Luminas they can equip. You will also earn one Lumina per character every time they level up.
You don’t need to keep an even spread of Lumina across all of your characters, especially if you keep your highest level Pictos on one character.
This menu also allows you to upgrade your three consumable Tints: Healing Tint, Energy Tint, and Revive Tint. Upgrading these Tints requires specific items, and each of these Tints can only be upgraded once.
How To Unlock The Curator And Weapon Upgrading
While you will begin to accrue Chroma Catalyst and Colour of Lumina early on in Clair Obscur, you’ll need to progress through a significant portion of the game before you’ll be able to craft weapons and upgrade your characters’ Lumina. In order to unlock the Curator in your camp, you’ll need to complete the Flying Water quest line.
This means you won’t be able to upgrade weapons until you’ve met up with Lune and found a way out of the Spring Meadows, then followed Maelle’s tracks into the Flying Waters and rescued her from the Curator’s mansion, and finally fought your way to the end of Flying Water and returned to the Continent hub.
It will take you approximately seven hours to unlock the curator – assuming you are diligently searching each area and taking on the optional challenges along the way.
How To Find Chroma Catalyst And Colour Of Lumina
Tints like Chroma Catalysts and Colours of Lumina can be found by exploring and can also be earned by defeating enemies. Search for glowing white and purple objects on the ground to find weapons, Pictos, and upgrade materials.
Side paths guarded by enemies will often end with a material reward like a Chroma Catalyst
. If you’ve reached a dead end without any reward, look for ledges to climb or grapple points to interact with. Pay attention to the haptics in your controller, as it will rumble when there is a grapple point nearby.
To put it simply, the more you fight enemies and explore, the more upgrade materials you will find.
