By default, QGIS visualizes all layers in the Single symbol setting. This means all the features of a layer are visualised the same. In this setting, you can change many parameters like colour or opacity but you can not classify any data!

To adjust the style of a layer…

• Right-click on your layer

• Click on Symbology

• Confirm that the layer setting is on Single Symbol

• Select the colour of your choice in the drop-down menu. For more colour options select in the drop-down menu Choose Color

• Optional:. You can adjust the opacity/ transparency of the layer. This can be very useful when you want to show multiple overlapping layers.

• Optional: Here you can set the unit type. This is usefull when you want for example visualize points in a certain size.

• Optional. Here you can find standard and previously used styles quickly.

• Click Apply to put your adjustment into effect.

• Click OK to close the window.
