# User Setup – Calendar Color Preferences
Resource Planner allows calendar cells to be displayed using different color classifications.
To configure the calendar colors:
1. Open **Resource Planner** from the left-hand navigation menu.
2. Select the **Config** tab.
3. Configure the required calendar color settings.
Calendar cells can be classified using one of the following options:
* **Resource**
* **Communication Action**
* **Communication Status**
After selecting the **RP Cell Colour** By classification, individual colors can be assigned to each value within that category.
For example, when **Communication Status** is selected, different colors can be assigned to statuses such as:
* **Cancelled**
* **Complete**
* **In Progress**
* **Pending**
These color preferences help users quickly identify the status of activities within the Resource Planner calendar.
### Show Color Legend
The **RP Show Colours Legend** option displays a legend that identifies the meaning of each color used in the Resource Planner grid.
When this option is enabled, users can quickly identify communications based on the selected **RP Cell Colour By** configuration, making it easier to interpret the calendar view.
**Lighten Color Condition and RP Lighten Factor**
The Lighten Colour Condition and RP Lighten Factor settings allow users to define conditions under which a communication is displayed using a lighter shade of its assigned color.
By default, the Lighten Colour Condition is set to:
**comm.comm\_companyid == null**
Using this condition, communications that do not have an associated company are displayed using a lighter shade of the assigned color.
The condition can be modified to use any communication field. For example:
**comm.comm\_status != 'Cancelled'**
This flexibility allows organizations to define custom conditions for displaying lighter colors based on their business requirements.
The **RP Lighten Factor** setting controls the degree to which the selected color is lightened when the specified condition is met. Together, these settings provide additional visual differentiation within the Resource Planner calendar.
### Business Hours – Calendar Settings
Resource Planner uses a **Business Calendar** that is created during installation. This calendar defines the organization's business hours and is used by Resource Planner when scheduling and displaying activities.
To configure the Business Calendar:
1. Navigate to **Administration → System → Timings**.
2. Select **Business Calendar**.
3. Open **Resource Planner**.
4. Update the required business hours and save the changes.
