20 Firefly symbols for points. This style is inspired by John M Nelson's ArcGIS firefly styles.

This style uses blur effect instead of outer glow effect as the latter needs to open deep level settings to change the color while this style color can be changed easily as like others. So, this style works well with random color and color ramp settings of Categorized and Graduated symbology methods.

Firefly symbology for lines and polygons are also available. Please find under respective style type or under "Firefly" tag.
