+# Decorators
+
+**Decorators** are classes that can encapsulate certain visual effects and then apply those visual
+effects to a sequence of canvas drawing operations. Decorators are not [Component]s, but they can
+be applied to components either manually or via the [HasDecorator] mixin. Likewise, decorators are
+not [Effect]s, although they can be used to implement certain `Effect`s.
+
+There are a certain number of decorators available in Flame, and it is simple to add one's own if
+necessary. We are planning to add shader-based decorators once Flutter fully supports them on the
+web.
+
+
+## Flame built-in decorators
+
+### PaintDecorator.blur
+
+```{flutter-app}
+:sources: ../flame/examples
+:page: decorator_blur
+:show: widget code infobox
+:width: 180
+:height: 160
+```
+
+This decorator applies a Gaussian blur to the underlying component. The amount of blur can be
+different in the X and Y direction, though this is not very common.
+
+```dart
+final decorator = PaintDecorator.blur(3.0);
+```
+
+Possible uses:
+- soft shadows;
+- "out-of-focus" objects in the distance or very close to the camera;
+- motion blur effects;
+- deemphasize/obscure content when showing a popup dialog;
+- blurred vision when the character is drunk.
+
+
+### PaintDecorator.grayscale
+
+```{flutter-app}
+:sources: ../flame/examples
+:page: decorator_grayscale
+:show: widget infobox
+:width: 180
+:height: 160
+```
+
+This decorator converts the underlying image into the shades of grey, as if it was a
+black-and-white photograph. In addition, you can make the image semi-transparent to the desired
+level of `opacity`.
+
+```dart
+final decorator = PaintDecorator.grayscale(opacity: 0.5);
+```
+
+Possible uses:
+- apply to an NPC to turn them into stone, or into a ghost!
+- apply to a scene to indicate that it is a memory of the past;
+- black-and-white photos.
+
+
+### PaintDecorator.tint
+
+```{flutter-app}
+:sources: ../flame/examples
+:page: decorator_tint
+:show: widget infobox
+:width: 180
+:height: 160
+```
+
+This decorator *tints* the underlying image with the specified color, as if watching it through a
+colored glass. It is recommended that the `color` used by this decorator was semi-transparent, so
+that you can see the details of the image below.
+
+```dart
+final decorator = PaintDecorator.tint(const Color(0xAAFF0000);
+```
+
+Possible uses:
+- NPCs affected by certain types of magic;
+- items/characters in the shadows can be tinted black;
+- tint the scene red to show bloodlust, or that the character is low on health;
+- tint green to show that the character is poisoned or sick;
+- tint the scene deep blue during the night time;
+
+
+## Using decorators
+
+### HasDecorator mixin
+
+This `Component` mixin adds the `decorator` property, which is initially `null`. If you set this
+property to an actual `Decorator` object, then that decorator will apply its visual effect during
+the rendering of the component. In order to remove this visual effect, simply set the `decorator`
+property back to `null`.

+[Effect]: ../../flame/effects.md
