## TL;DR

Remove the # from all pageSettings color values. Use "ffffff" instead of "#ffffff" for backgroundColor, primaryColor, and textColor: ``js pageSettings: { backgroundColor: 'ffffff', primaryColor: '00a2ff', textColor: '4d5055' } `` The reporter confirmed this fixed it.

## Steps

1. Remove the `#` from all pageSettings color values. Use `"ffffff"` instead of
`"#ffffff"` for `backgroundColor`, `primaryColor`, and `textColor`:

```js
pageSettings: {
 backgroundColor: 'ffffff',
 primaryColor: '00a2ff',
 textColor: '4d5055'
}
```

2. The reporter confirmed this fixed it.

## When to use

You are seeing this: After upgrading react-calendly to v3, the onEventScheduled callback on CalendlyEventListener stops firing. Use this skill when you run into "react-calendly onEventScheduled stops working when colors have #".

## When not to use

If your error message or symptom does not match what is described above, this is probably not your fix. Search for your exact error text instead of forcing this one to fit.

## Versions

Versions mentioned in the source: 2.1.0. If you are on something much newer or older, the details may have shifted.

## Why this happens

The original report does not dig into a root cause. It documents the symptom and the fix that resolved it.
