After months of planning and preparation, the perukā Watercolor Gradient Online Course is finally here. This is an exclusive, self-serve, prerecorded course sold by Sweetie Nail Supply in collaboration with perukā.

This course mainly focuses on 14 watercolor gradient designs, all created spontaneously during recording. This course has been designed by the founder of perukā, @cookie.n_ails on Instagram.

Each nail design starts from a light, transparent base and gradually builds up to more complex layering.
If you prefer soft and sheer watercolor effects, you can stop anytime within the first 1–2 layers.

The video will not focus on analyzing or explaining the placement of color blocks. Instead, the emphasis will be on watercolor usage techniques and layering methods. Every design is demonstrated fully from start to finish, with no edits or cuts.

If you’ve been wanting to learn watercolor gradients and also love these 14 designs, this course is perfect for you .

This course is recorded first and then dubbed with narration afterwards.
Important steps and key application tips will be explained in detail, including:
• Water control, ratios, and base preparation suggestions
• Application tips when working on clients’ nails
• Demonstrations using nail tips directly for clearer understanding

(For each type of material, the first design will include more detailed explanations. Repeated materials and techniques later will not be explained again.)

The course features perukā’s new “Non-Wipe Matte Watercolor Top Coat”, which has been tested for over half a year to achieve the ideal watercolor matte effect.
It not only preserves colors beautifully but also allows watercolor to dry quickly on the surface. Please note that the Non-Wipe Matte Watercolor Top Coat is sold separately. You can find the product here.
"I’m very satisfied with the gradient results it creates" - perukā's Founder

The course will demonstrate 3 types of materials combined with the perukā Matte Top Coat:
· Watercolor: 7 designs
· Blending liquid: 4 designs
· Colored pencils: 3 designs

"This course is packed with content, and I believe you will love it" - perukā's Founder

Note: When applying the Matte Top Coat, small particles may appear on the surface. This is normal and will disappear after curing.
If you cannot accept this, please do not purchase the course or product.

"Even if you don’t plan to apply directly on clients’ nails, this course will still be valuable.
I have always believed that using watercolor-based materials on nail tips can greatly improve:
· Aesthetic sense
· Sensitivity to color combinations
· Freedom in daily creative work

I hope this course encourages you to step outside the usual gel framework, bravely experiment with different artistic mediums, and discover your own joy and inspiration through the exploration of colors." - perukā's Founder
