The best way to color rice: a comparison of two methods

We all know that I love rainbows (you can find all of our beautiful rainbow activities here)...so of course I can't resist rainbow rice! Traditionally rainbow rice is made using food coloring and vinegar, but S and I wanted to know what it would look like using our Discount School Supply tropical colored Colorations Liquid Watercolors (What are Liquid Watercolors?) so we gave it a try.


If you have an infant or toddler who is prone to sampling, I'd stick with the plain rice for rice play myself.  Once they are not so tempted (or if you are willing to watch them vigilantly as we had to do with X - that rainbow rice looks tasty!), rainbow rice is a fun way to mix it up.  I personally can't stop staring at our newest batch!

To make colored rice of either variety, we start with a Ziploc bag (we use the freezer kind because we tend to make large quantities at once) full of whatever amount of rice we're looking to color.  Add the rice and then:

If using Colorations Liquid Watercolors add directly the amount of color you want.  If you shake the bag and some grains of rice are still white, add more color.  The more color you make, the richer the color will be.  You don't want to soak the rice, however.  For the amount seen below I used three squirts of pink.

If using food coloring, add a hearty amount and add a small bit of vinegar.  For the amount of rice pictured below, I'd add around a teaspoon of vinegar.  The vinegar helps spread and set the color.  If you still have some white grains of rice, add more food coloring (and/or vinegar).  The more food coloring you add, the darker the color of the rice will be.  You are not aiming for wet rice - but you are aiming for uniform color.

After adding the coloring, hand the bag to the nearest toddler/preschooler for shaking.  :)


I like to make one color at a time, rinsing the Ziploc in between each color to minimize the waste generated.


As each color is completed, I lay out a sheet of wax paper on the counter and spread the rice as thinly as possible.  As it dries, we mix it up with our hands to make sure all the grains have a chance to air dry.  The rice pictured below was colored with our liquid watercolors.


Ooh!  So pretty!  I couldn't resist a close up of our tropical lime green rice.  :)


Here's our color comparison.  The rice on the left was made with tropical liquid watercolors.  The rice on the right was made with food coloring and vinegar.  I felt like the Colorations Liquid Watercolors did a better job of totally coating the grains and therefore produced more vibrant colors.  Our liquid watercolor rice (probably in part to the "tropical" coloring) almost glowed!  It was so bright and cheerful and inviting.


Here's a grain by grain comparison.  Though the red and yellow food coloring did a pretty good job, I think overall the liquid watercolor rice had better coloration.  There's also the smell...the food coloring rice definitely smells of vinegar.  It's faint, but still there.  The theory is that the vinegar will keep the rice from growing mold; however, I have had vinegar colored pasta mold because we stored it before it had completely dried out.  I think the most important thing, regardless of what method you use to color your rice, is to be sure to give it ample time to completely dry.  I'd say at least a day of sitting out in open air before sealing it in a storage container would be ample to discourage mold.


Though either way produces beautiful and enticing rice, our favorite method was Colorations Liquid Watercolors   It was easier (no measuring), has no scent (no vinegar!), and produced more vibrant colors.  I also suspect that it is ultimately more cost effective because food coloring is expensive and coloring rice requires quite a bit of it!

    1. Yes and yes! I find it to be MUCH easier than food coloring and vinegar, too.

  3. We made this and made it with the watercolors from colorations too. I tried to make silver - but that just ended up looking grey and not silvery or sparkly at all. I might try some of the 'make it glitter' or 'make it shimmer' range with the next batch and see if we can make sparkly rice. It was super easy and amazing colors & hugely entertaining for the girls - both the making & playing!

    1. We love the vibrant colors so much more with liquid watercolors - and yes, so much easier! Bummer about the silver - we've never seen the silver liquid watercolors before - I am now intrigued! Cool idea to try the glitter/shimmer. Let me know if it works! :)

  4. I love rainbow rice! We use alcohol hand gel on our rice instead of vinegar - it stops the colour from coming off and it doesn't smell of anything. Love the colours you get from the liquid watercolours. Lovely blog :)

    1. Rainbow rice is the best! That's a great idea! I recently read of another blogger who uses scented hand gel to make it smell great! I am too addicted to our liquid watercolors to go back to food coloring to give it a try, though, LOL.

  6. Where do you buy all your rice? I have only seen maybe 3 lb bags at the market and it was not cheap.

    1. Safeway generic brand in the large bags tends to be a bit cheaper. I've also gotten some from Grocery Outlet (around $15 for 20 lbs I think) and from the Dollar Tree ($1 per pound). Overall it isn't the cheapest - but it does last nearly forever! We still have a batch of rainbow rice from when S was 2 and it's in great shape. We keep it sealed in shoebox storage container. As long as you don't get it wet, it should keep for quite some time.

    2. I know this reply is very late, but our WalMart has 20 lb bags of rice for less than $10.

  7. I use colorations and rubbing alcohol. Helps to not saturate the rice and dries quicker. I have 6 bottles of the ra that I keep one for each color. Any leftover liquid can be put back in the bottle and saved.

  8. Two questions:
    Have you ever tried using fluorescent watercolor paints to make rice that glows in a black light?

    Have you ever used the liquid watercolors from Dick Blick? (and yes, these questions are related as Dick Blick does sell fluorescent liquid watercolors)

    1. No, but it's definitely possible! I haven't tried any of the Dick Blick kinds, so I couldn't say for sure whether or not they would work, but if they fluoresce under a blacklight, they'll work for glowing rice!

  9. While working as a resource coordinator at a half day preschool I used the Colorations liquid watercolor all the time. I absolutely LOVE that stuff. I used it to color rice, pasta, play-dough, popsicle sticks, glue, shave cream, bubbles, water and then froze it different containers, water for water play and used it in bingo dabbers. The list is endless. Did I say I love this stuff? :)

  10. Does the color from either method transfer to hands or clothing?

    ReplyDelete
    Replies
    1. Only if you get the rice wet. If your hands/clothes and the rice are all dry no color transfers. :)
