Painting a Cartoon Style Rainbow Unicorn
This Rainbow Unicorn is painted on icing in a cartoon style using a poster painting technique. If you know how to paint on icing you can add any images you want to a cake and this tutorial will lead you through the stages to get a great finish. This is one of the simplest forms of painting on icing and a great place to start! You use blocks of colour to build up the Rainbow Unicorn image. A little shading adds basic detail.
For this Rainbow Unicorn I have traced out the design and transferred it to a plaque using the edible pen technique (tutorial for this coming soon). You can do this straight onto your cake if you prefer.
At the end of this post you will find a video showing the whole process.
You will need:
- Rainbow Dust Pro Gel Colours in Pink, Baby Blue, Aqua, Purple, and Yellow
- Rainbow Dust Icing Whitener
- Alcohol, Water or rejuvenator fluid for mixing
- Paint Palette
- Good quality sable brushes
- Rainbow Dust Jet Black Food Art Pen
How to mix the colours
Start by adding some icing whitener to your palette
Add a spot of each colour to the centre and mix a little into the powder using water or alcohol
You will need:
- Pale pink for the body
- A deeper pink for shading
- Blue for the horn and hooves
- Yellow, Purple, Deep Pink, and Aqua for the mane and tail
How To Paint the Body
Load the sable brush with pale pink colour. This should be liquid enough to flow smoothly as you paint so adjust the thickness if you need to. Follow the shape of the unicorn’s body and use long even strokes to paint the pink all over the body, head and legs. Add more colour to your brush when you need to.
Then using the deeper pink colour – this should be a few shades darker – don’t make it too dark!- add shading detail to the head, underside of the legs and body and around the back of the unicorn.
Using a little more of the pale pink blend the edges of the shading so there is no obvious line between the two pink colours.
How to Paint the Horn and Hooves
Using the pale baby blue fill in the whole area of the horn an hooves. Then darken the blue a little and paint in the shaded detail – a line down the horn and the edges of the hooves.
Painting the head detail
Mix a little of the pale yellow with a little pale pink to make a light flesh colour and paint the muzzle of the unicorn
Add some deep pink to this and paint the inside of the ears.
Using the deeper baby blue paint the eye
How to Paint the Mane and Tail of the Unicorn
Using the deep pink paint a stripe down each section of the mane following the flow of the outline. Do the same with the tail.
Add a stripe each of purple, yellow and aqua until the mane and tail.
are complete. Finish the tail with a thin stripe of pink on the top
Using a very pale yellow brush around the base of the unicorn so he looks like he is sitting on something rather than floating in the air!
Leave to dry completely
How to Complete the Rainbow Unicorn
When the painted unicorn is completely dry outline carefully with the thicker end of the Rainbow Dust Food Art Pen. Use long strokes if possible for a smoother finish. Draw in the eye leaving some of the blue visible and add lashes. You can add a small white dot in the eye using the Icing whitener powder to add life to eye if you like.
I have used the black pen to emphasise the cartoon nature of the painting however you can use a pale grey or pink pen if you prefer a softer look.
If you want watch the whole process I have added a video of how the Rainbow Unicorn was painted so check that out below:
