HUGE Rainbow Flow 

Acrylic Pouring🌈

Acrylic Pouring Tutorial by Olga Soby​

Rainbow Colors - Just Paint & Water - Bright Fluid Painting

Let’s create a HUGE Rainbow Flow Acrylic Pouring today! I’m going to be working on this huge 40 by 30 inches canvas. This is a commission fluid abstract artwork. My client wanted me to create something in sort of a Dutch Pour style with some blown and airy elements in the colors of the rainbow. 


So, this is going to be fun! And I have an idea that I’m going to do a sort of diagonal flow, where each color of the rainbow will slowly transition into the next one. I might work on the corners as well, but first I want to create my rainbow flow and see how the composition of the whole pour painting works out. Also, all of my colors today are mixed with just water, no other additives. Of course, there’s gonna be seven main colors.

Acrylic Pouring RECIPE used for today’s flow art painting:​

Acrylic paint is mixed with water only to a fluid consistency. I add approximately 30-50% of water to my colors. There is no exact % or proportion because this ratio depends on initial paint viscosity, which significantly varies from brand to brand and even from color to color.

But for some of the colors, I got few different shades: for red, for violet, for blue to make it look more interesting, so it’s not just too flat. I want to position my rainbow diagonally. I have it sort of in a curvy motion. This is going to be a very abstract and modern fluid painting. I want to have red at the top and purple violet at the bottom. I think I am going to start with just my rainbow colors and then I will work on these two corners after. And now let’s create that rainbow! This is going to be fun!

Isn’t this abstract pour painting gorgeous? My rainbow flow that wins the storm! I am totally crazy about this fluid painting. It dried beautifully and the colors have even more contrast and definition. And most importantly my client loves it! So, what I really love about it is that each fragment, each color has its own character, its own unique features. Yet everything is connected in one flow. 

I hope you enjoyed the process and looking forward to hearing from you! Happy creating!
