An effect is an automated movement or change of color. In other words, it is an automated modulation of attributes. 

**Example:**

Dimmer channel that runs the fixtures in a sinusoid between two values – high and low.

## []()Effect Modes

There are four effect modes that are displayed in form of letters in the upper right corner of each object in the effect pool:

- **A:**\
  A stands for an absolute effect. It moves in an absolute manner between the low and high values. 
- **R:**\
  R stands for a relative effect. The low and high values are added onto the actual value. 

**Hint:**\
Relative values are mainly used in pan and tilt. 

- **S:**\
  S stands for a selective effect. It is only valid for fixtures that are linked to this effect. 
- **T:**\
  T stands for a template effect. It is valid for all fixtures that contain the attributes of a particular effect.

For more information on the selective and template effects see [Use template and selective effects](/grandma2/key_effects_template_and_selective/).
