What makes a brush glow?
A convincing neon brush is built in two parts: a bright, near-white core line, and a soft colored halo around it that bleeds into the dark. The glow comes from that soft outer light combined with a dark background and a blend mode like Add or Screen. The best neon brushes bake this in so one stroke reads as a lit tube.
The neon brush types you need
1. Neon tube / line
A glowing line with a bright core and soft halo — the workhorse for neon signs, outlines and light trails.
2. Soft glow / bloom
A soft, diffuse brush for adding atmospheric glow and bloom around lights and edges.
3. Spark and dot lights
Tiny bright points for bokeh, sparks, stars and electric detail.
4. Light leak / haze
Wide, soft washes of colored light for backgrounds and mood.
What to look for
- Bright core + soft halo built into the brush.
- Reads on dark — neon needs a dark background to glow.
- Color-shifting — a core that stays light while the halo takes your color.
- Layer-friendly — works on Add/Screen blend layers.
How to use neon brushes
- Work on a dark background — neon doesn't glow on white.
- Draw your line on a layer set to Add or Screen.
- Add a soft glow layer beneath for the halo.
- Drop sparks and bloom for atmosphere.
