Dyeing fabric with food colouring is a simple and cost-effective process, especially if you only want to dye part of the fabric. It is possible to use gel food colouring to dye fabric, but it is worth noting that gel food colouring is almost impossible to remove from fabric. It is also important to consider the type of fabric being used, as food colouring works best on fabrics with protein fibres such as wool, silk, and cashmere. If you are looking to dye fabrics like cotton or linen, it is recommended to use fibre reactive dyes from dying kits.
Characteristics and values of using gel food coloring in fabric paint
| Characteristics | Values |
|---|---|
| Effectiveness | Gel food coloring can be used to dye fabric, but it is not ideal for fabrics like cotton and linen due to their cellulose composition. It works best on protein fibers such as wool, silk, and cashmere. |
| Ease of use | It is a relatively simple and cost-effective process, especially for beginners. It allows for precise control and distinct shapes when used with a stencil. |
| Durability | Gel food coloring can be challenging to remove from fabric. The color can last for years in dyed clothes when locked in with vinegar and heat treatment. However, some discoloration over time and with washing can be expected. |
| Mixing | When mixed with acrylic paint, gel food coloring may not dry properly and can remain sticky, separating from the paint. It is important to test the mixture on a small area first. |
| Alternatives | Other options for tinting paint include using acrylic ink, tie-dye, or purchasing pre-mixed tinted paint. |

What You'll Learn
Using gel food colouring to dye fabric
Dyeing fabric with gel food colouring is a simple process, but it works best on fabrics with protein fibres, such as wool, silk, cashmere, and feathers.
First, soak the fabric for a few hours in a solution of water and clear vinegar. For every 100g of fabric, use a quarter of a cup (60ml) of vinegar. If you are dyeing a small amount of fabric, a few squirts of vinegar will suffice.
Next, mix the gel food colouring in a cup of hot water. You will only need a small amount, and it is important to make sure that it is fully dissolved. Add the dye to a pan of water, along with a few more squirts of vinegar, and mix well.
Afterward, add the fabric to the pan, ensuring that it is completely submerged. Heat the mixture slowly until it reaches a simmer. Let it simmer for about 20 minutes, or until the fabric is the desired colour.
Finally, remove the fabric from the dye and let it cool down. This step is especially important if you are dyeing wool or silk. Once it has cooled, rinse the fabric, and you're done!
It is worth noting that gel food colouring will not wash out of the fabric, so be cautious when choosing the colour and fabric. Additionally, some colours may stain the fabric, so it is recommended to test on a small area first.

Mixing gel food colouring with glue
While I could not find much information on mixing gel food colouring with glue, I did find some sources that describe a technique for dyeing fabric with food colouring and glue gel resist. This technique involves adding a few drops of liquid food colouring to school glue gel to create a distinct shape on a piece of fabric. The food colouring can then be washed away with the glue, leaving no stain on the fabric.
- Tape a stencil with a simple design to the underside of a silkscreen frame.
- Pour 1/3 cup of blue school glue gel into a small container and add 2-3 drops of liquid food colouring. Mix well with a plastic spoon.
- Use a squeegee to drag the coloured glue across the surface of the silk.
- Tape the printing surface to a worktable to keep it from shifting.
- Pin or tape the fabric to the printing surface with the glue side facing up.
- Use a credit card, squeegee, or foam brush to move the paint across the cloth.
- Set the fabric aside to dry for 6-12 hours.
- Once dry, heat set the fabric from both sides with a dry iron, following the manufacturer's instructions.
- Soak the fabric in water for an hour and then wash it by hand or in a machine with mild detergent.
- Air-dry and press the fabric.
It is important to note that this technique is not recommended for use with gel food colouring, as it is almost impossible to remove from the fabric. If you want to use this technique on silk, choose green, red, or yellow food colours, as blue food colouring will tint the fabric and will not wash out.

Applying gel food colouring to silk
Food colouring can be used to dye silk, and it is a relatively simple process. It is a good method for beginners as it uses familiar household objects and is cost-effective. Food colouring will remain in silk for years, as the process of using vinegar and heat locks in the colour.
Firstly, you need to soak the silk in a solution of water and vinegar. A rough guide is a quarter cup (60ml) of vinegar for each 100g of fabric. You then need to mix the gel food colouring in a cup of hot water, ensuring it is fully dissolved. Next, add the dye to a pan of water, along with a few more squirts of vinegar, and mix well. The fabric should then be added to the pan, ensuring it is fully submerged, and heated slowly until simmering. The silk should then be left to simmer until it reaches the desired colour. It is important to then let the silk cool down before rinsing.
It is important to note that silk is best dyed with anionic food dyes, and larger, more hydrophobic anionic dyes are usually used in commercial silk dying. The temperature should not exceed 80-85°C to avoid damaging the silk.
Another method for dying silk with food colouring involves using a glue gel resist. This method can be used to create precise shapes and distinct designs. The glue gel is mixed with a few drops of liquid food colouring, which can then be applied to the silk using a stencil. This method does not require heat, but the glue must be heat set using an iron to obtain a clear resist.

Combining gel food colouring with acrylic paint
It is important to note that tinting paint with gel food colouring can be challenging, and the resulting colour may not match your desired shade. This is because the tintability of paint depends on the specific "base" of paint used. Additionally, gel food colouring may not be as colourfast as traditional paint dyes, and the colour may fade over time, especially when exposed to oxygen and UV radiation.
If you decide to combine gel food colouring with acrylic paint, it is recommended to mix the colouring with acrylic art paint first, before adding it to the base paint. This can help improve the mixing process and create a more consistent colour. However, it is always a good idea to test the mixture on a small area first to ensure that the colours do not separate and that you are satisfied with the resulting shade.
Overall, while it is possible to combine gel food colouring with acrylic paint, it may require some experimentation to achieve the desired results. It is important to manage your expectations and be prepared for the colour to fade or separate. In some cases, it may be more cost-effective and efficient to purchase pre-mixed paint in the desired shade rather than attempting to mix it yourself.

Pros and cons of using gel food colouring
Gel food colouring is a popular choice for creating vibrant and colourful treats, especially during the holidays. It is made with synthetic colouring and has a water, glycerine, and/or corn syrup base, resulting in a thick, gel-like consistency. Here are some pros and cons of using gel food colouring:
Pros:
- Gel food colouring is highly concentrated, so you need only a small amount to achieve intense and vibrant colours. This makes it cost-effective and helps minimise the risk of altering the flavour or texture of the food item.
- It is ideal for recipes where you want to minimise the amount of liquid added, such as in candies, frostings, or icings.
- Gel food colouring is available in a wide range of colours and can be purchased online, at craft stores, or at kitchen stores.
- It is effective for dyeing large amounts of batter, such as cake batters, and can produce dark, saturated colours.
- Gel food colouring is perfect for creating intricate designs and decorations on cakes and achieving impressive ombre effects.
Cons:
- Due to its thick texture, gel food colouring can be challenging to incorporate into thick or stiff doughs, like cookie dough.
- It is easier to add too much gel food colouring, which cannot be undone, and some people may not like the taste of certain colours, like red.
- Gel food colouring may be harder to find in some locations, and natural food colourings can be especially difficult to source, requiring a visit to specialty stores or online shopping.
- The darker colours of gel food colouring may not be as intense as expected, and the colouring may appear as flecks or dots within the frosting.
