How to Make a Neon Glow Effect in Procreate

Glow in Procreate is not a brush you buy. It's a layer recipe, and once you've built it once you can make anything radiate: neon signs, bioluminescent trees, fireflies, floating seeds. Freya builds glows two different ways across her Neon Garden Landscapes course and her Procreate Pocket animation exercise, and both come down to the same two ingredients: blur, and an additive blend mode.

Rule One: Start Dark

Neon only reads against darkness. In the Pocket neon sign exercise, Freya starts with a black background and then does something clever: she imports a photo of her own wall, drops its Saturation to zero, brightens it slightly, sets the layer to Lighten and reduces its opacity. The faint wall texture is what later makes the glow feel like it's actually mounted on something real.

The Core Recipe: Duplicate, Blur, Add

Here is the engine behind the whole effect, exactly as Freya builds the word "Let's" in glowing pink script.

1. Write your text on its own layer in a light color. Freya uses her Freya Wired Monoline brush in light pink, writing by hand rather than typing.
2. Duplicate the layer four times, so you have five copies, and rename them 1 through 5.
3. Leave layer 1 untouched. That's the crisp tube of the neon light.
4. On layer 2, fill the letters with a darker pink, apply Gaussian Blur at about 5% (Adjustments, Blur), and set the layer's blend mode to Add.
5. On layer 3, blur at about 10%, darken the fill again, and set it to Color Dodge.
6. Layers 4 and 5: blur at roughly 15% and 20%, darker fills, Color Dodge again.

Each copy is a wider, softer halo behind the same shape, and the Add and Color Dodge modes make them pile light on top of light. The tighter blurs give the hot core; the wide ones give the ambient bloom on the wall. The two modes are not interchangeable, either: in the lesson you can watch Add produce a gentle glow, then Color Dodge on the next layer make it, in Freya's words, much brighter and very distinctive. If any layer screams too loudly, refill it with a darker version of the color rather than lowering the blur. When the stack gets messy, select all five layers and group them.

Freya finishes the sign with a second word, DANCE, made with the text tool: duplicate the text, set one copy's style to Outline under Attributes, rasterize both, then dot small bulbs along the outline with her Dotted Line brush before running the same blur-and-dodge stack. One extra touch is worth copying: she puts a heavily blurred Color Dodge copy underneath the sharp text, so soft light spills out from behind the letters.

The Painterly Way: An Add Layer on Top

The duplicate stack is perfect for signs, but for organic glow Freya paints it instead. In the Neon Garden course she builds a glowing tree with curtain-like boughs, then creates a new layer above it, sets it to Add, and strokes a bright pink along the base of each bough with a soft light brush. The strokes bloom into light exactly where the boughs begin, fading as they fall.

"Please don't overdo it. Otherwise it's going to be too bright and cover all the nice detail of the boughs."

That restraint is the difference between glow and glare. The Add layer multiplies whatever you give it, so give it very little.

Glowing Details: Fireflies and Light From Inside

Two more tricks from the Neon Garden course finish the vocabulary.

Fireflies are the cheapest glow available: Freya taps single dots with a Lightpen brush from Procreate's Luminance brush set, varying the size, some clustered, some scattered. Luminance brushes carry their own glow, no blur stack needed. She repeats them in mint green, sky blue and pale pink across different depth layers of the scene.

Light from inside uses Alpha Lock. For her floating plants, she locks the plant layer's transparency, then brushes a soft pink right where the roots meet the cup of the plant. Because of the lock, the light lands only on the plant itself, and the more passes she makes, the brighter that core gets. The object appears to be its own light source.

Framing the Sign with Bulb Lights

Around the two words, Freya adds a border of small yellow bulbs, and the technique is a nice QuickShape crossover. With the Dotted Line brush on a fresh layer, draw each side of a triangle and long-press at the end of the stroke so it snaps straight, then tap Edit Shape to nudge the lines into place. Erase the dots that overlap the letters, duplicate the layer twice, and run the same recipe: 5% blur set to Add, 10% blur set to Color Dodge. The frame glows like a string of marquee lights.

Bonus: Make the Neon Blink

The Pocket lesson ends by animating the sign. Copy the whole canvas, paste it into a fresh project, turn on Animation Assist (Actions, Canvas), and set that pasted image as the background frame. Then add a frame, dab one bright starburst on a single bulb with a Rising Star brush set to Add, duplicate the frame, and move the star to the next bulb with Transform. Repeat around the sign, set the playback to Loop, and the light chases around your sign like a proper storefront.

Freya makes a point of noting the entire exercise was built on a phone. None of this needs an iPad Pro.

Where This Leads

Everything above is technique you can apply tonight. The full Effortless Neon Garden Landscapes course goes further: whole glowing scenes with layered lands, custom branch and foliage brushes, and a finale where the finished illustration becomes a dimensional animation. If glowing botanical worlds are your thing, the free lessons from that course show you Freya's process before you decide. 🎨
