Hi there!, Ive been struggling with this for a long time, since im a newbie. I know this has been made using acrylics, but what technique? using air? paint straight from the bottle?
Thanks a lot
This is another example
Where did you find these images? Online? I ask this because of the hard edged line on the multicolored one.
For the first one...notice the area between the yellow and red, it slightly blends together. Notice the blue/cyan areas. There appears to be some of this marbled effect going on.
Keep in mind you will not be able to duplicate these exactly, but can get close. So it is time to experiment.
You will need some acrylic ink or acrylic which is watered down and you will also need full strength acrylics.
Lets start with the black one.Notice how it looks like spilled milk on a slick black marble floor? This is achieved by splashing and either blowing or moving the surface. (It doesn't drip, so don't hold it vertically. Keep it pretty much flat except for a little shaking.) I would start with a very smooth surface and paint it black. It should be as smooth and slick as possible.That means you could use black ink or enamel paint, spray painted. Lots of different paints will do. Even black paper that is smooth and non-absorbent will do. That's the key- jet black, super smooth and non-absorbant. After the jet black surface is dried, tape it to a flat surface around all the edges. You may even try spraying the black with crystal clear or a varnish. Now using watered down white acrylic ink.It should be almost clear as if you washed out a paint brush in a glass of water - make a few drips onto the surface from above- not too many say ten or so. Let this dry. Now take white ink that is more opaque and splash onto the black paper from a few feet above say about three or four large ones. Use a fan, blow through a straw or get really close and blow hard to spread the paint outward, rock the surface a little like your shifting sand. I would suggest starting with only a few splashes to see what effect you get.
For the first effect. (This one is harder because I'm seeing it digitally and the edges are very clean. There could be some photoshopping going on.)
Here are a few things to try:
Using thick opaque paint and a wide flat brush paint a yellow stripe. Then, paint a red stripe beneath this stripe but slightly overlap the yellow so that it blend. Now paint a cyan stripe under the red also slightly overlapping so the colors partially mix. Now you can take thinner blue acrylic and create a puddle onto the cyan and drop some other blues into the puddle.
Here is another thing to try. On a piece of paper use clear water to make a shape. The interesting thing is, if you drop acrylic ink into the wet area, the color will spread only within this shape providing it is not too wet. You could even paint a line with water and drop yellow acrylic onto the line, then put reed next to it, then put blue next to this and you will get a rainbow effect.
So essentially you have a blob of clear water - not a puddle. brush in yellow at the top (not too thin of a consistency of paint) and red underneath it, and cyan under the red.
You could also try lining up a blob of yellow next to red, next to cyan with drip of blue inside and then tilt the surface forward allowing the paint to drip downward. The consistency of this paint should be like clay slip or hot fudge so that it moves very slowly. Unlike the one on black, my guess is that a thicker liquid was used.
Hope this helps. You will need to experiment.
Did you get a chance to try this?
