The Color Fantasy of Acid Dyes

acid dye CMYK

Colors in fashion are used to attracts attention and create an emotional connection. In most of the situations, we associate Danger with Red, Cool with Blue, Warm with Yellow, etc. And they are also associated with nature and seasons like the Red is representing Fire, and Yellow is mostly used in Fall.


In bra making, we also try to match our lace, fabric, and findings in cohesive colors or complementary colors to create a different feeling that we are after. But, there is a limited choice of colors that available on the market, or some are just out of our budget.


Therefore, acid dyes have been very popular. They are very economical and easy to play with. Lucky for us, that most of the elastics and fabrics in bra making contain nylon, which can be easily dyed by acid dye. Not to mention, some of the rings and slider are nylon coated too, which mean they can be dyed too. However, the percentage of nylon content can affect the color deposit on the material and create variations in hues.


Ok. let's start with the fun part. I won't be spending too much time on how to dye with acid dye. Because lots of people have done this topic already, and the lovely liz_sews even made a YouTube video about it that you can check out here. I also link the Jacquard Acid Dye Instruction FYI.


Today's blog is about color mixing. I'm going to show you how you only need 4 colors to create endless color combinations. Let's gets into the Color Fantasy of Acid Dyes.


The four colors that required here are Turquoise (Cyan, C), Hot Fuchsia (Magenta, M), Sun Yellow (Yellow, Y), and Jet Black (Black, K) from Jacquard Acid Dyes. The first three colors are primary colors. They are used to create secondary colors like green, orange, and purple. And then you can mix them again and again to create endless colors. The black dye is used to create different hues.


So I'm using the CMYK color system to create my colors. The ink printer is the most common one that using this color system. And the color codes are very easy to find online. For example, I want to make color Celadon, the composition I found is C23.6, M0, Y22.2, and K11.8. Well, It's difficult to weigh such a small amount of dye in decimal. So I just use the whole number 24, 0, 22, and 12. You can use this website to check the color. But how can we mix the colors?


For example, our small White finding kit is 50g and the large white finding kit is 55g. So we only need 0.5g of the acid, it seems impossible to mix the powdered dyes in such a small amount. However, it is possible if we make all the colors in a 1% stock solution. What is a 1% stock solution? So you use 1g of acid dye diluted in 100ml of water. This is perfect for 100g of dry material. In our case, our finding kit is only 50g, so we just need 50ml of our 1% stock solution.


Ok. Let's making Celadon color, we need 1% stock solution of C, Y, and K. Then pour 24ml of C, 22ml of Y, and 12ml of K into a glass beaker. So the total is 24+22+12=58ml. It is slightly higher than the 50ml but close enough.


Now you just need to follow the acid dye instruction to dye your findings. The dye you are going to use is the mixed solution instead of the dry powders.

 And here you go. We got this beautiful green color.
