Holographic and Iridescent brushes – Complete Walkthrough

A walkthrough and tutorial for my new Holographic and Iridescent brush system for Procreate. In this video, you can look over my shoulder while I demo the brushes and describe their properties.

These color shifting brushes provide a sprinkling of magic to any project – whether it be gemstones, dragonfly wings, mermaid tails, or “oil slick” art. The possibilities are endless! Try these brushes out today, your inner child will thank you 😊

This brush set contains two versions (Holographic and Iridescent) of the same 40 brushes. Both versions have color changing properties but they differ in the range of color change.

Holographic – A broad range of colors that gets even broader with pressure applied, so that nearly the whole rainbow can come out in one stroke. Great for high-drama, colorful projects and unpredictable “happy accidents.” Take for instance the range of visible color in an opal gemstone.

Iridescent – The brush texture shows up in one main color of your choice, but also shifts to nearby colors on the color wheel. Iridescent brushes are ideal for projects where you want to have more control. A good example of this is a labradorite gemstone which has a more specific color range (blue, green, yellow and pink).

Important Note: If you use any of the brushes in this set on top of one another, they’ll get shinier and lighter because they are metallic. If you want to layer multiple brush strokes and colors on top of each other, always use a new layer.

A word on color: – Choosing lighter colors will give you a lighter rainbow. If the color is barely showing up, pick a darker color. – Choosing very saturated colors will give you more of a color range, whereas less saturated colors will give you a more metallic look. You can always experiment with the saturation of your colors in the value tab, using the “s” slider. The Iridescent brushes have less color variation than the Holographic, but if you want even less you can tap the brush name (under the Iridescent folder) to bring up the brush settings. Choose the “Color Dynamics” option on the left, and under “Stamp Color Jitter” bring the hue slider down to a smaller percentage. I’ve tried to name the brushes in this set as logically as I can. I won’t demo them all in this video, but hopefully the names are intuitive. I will describe a few of the brush types below.

Gradient – These soft and textured gradient brushes make excellent choices for backgrounds, lettering, and web graphics. Texture Brushes from Shimmering Silk to Crosshatch – These brushes each have a different texture and are named after the texture they were inspired by. These are great for mixing and matching within the same piece for texture variety.

Foil – Including many iterations, all shiny! We’ve got thin and thick foil lines, cracked foil, and so on.

Glitter – With varieties include Glitter Flakes and Glitter Sketch, Solid Glitter, Loose Glitter, and Confetti, these are great for a finishing touch on any piece, for instance adding iridescent glitter to dragonfly wings.

Lettering – in the Holographic version, there’s a slight color change as more pressure is applied, so that your up strokes and down strokes look different. The Iridescent versions do not have this feature, and will give you unchanging iridescent color no matter how much pressure you apply.
