# Migrating from WSC 5.4 - TypeScript and JavaScript
+## `WCF.ColorPicker`
+
+We have replaced the old jQuery-based color picker `WCF.ColorPicker` with a more lightweight replacement `WoltLabSuite/Core/Ui/Color/Picker`, which uses the build-in `input[type=color]` field.
+To support transparency, which `input[type=color]` does not, we also added a slider to set the alpha value.
+`WCF.ColorPicker` has been adjusted to internally use `WoltLabSuite/Core/Ui/Color/Picker` and it has been deprecated.
+
+Be aware that the new color picker requires the following new phrases to be available in the TypeScript/JavaScript code:
+
+- `wcf.style.colorPicker.alpha`,
+- `wcf.style.colorPicker.color`,
+- `wcf.style.colorPicker.error.invalidColor`,
+- `wcf.style.colorPicker.hexAlpha`,
+- `wcf.style.colorPicker.new`.
+
