Dyeing an array of fibres orange-brown

Further to my post of a few days ago I have now decided what I am going to do with the combed Llandovery Whiteface Hill fibre.  I decided to split the fibre into 4 lots of around 155g each and add the same fibres to each lot but in different colours so that I can dye the fibre an appropriate colour and make 4 yarns that are almost identical but just in different colours.  The total amount of fibre in each lot will be enough to make 2 skeins of yarn and a nice amount to make a shawl.

I started out by sorting items from my ingredients cupboard into colour groups and then checking if I had at least 4 different colours of any given fibre.  Where I didn't have the necessary 4 colours that fibre was eliminated from the piles.  Next I had to decide which fibres in each colour group worked well together, such as which shades of blue out of all of the packets looked good together.  I ended up with 5 piles of 4 small packets of fibres so I had to eliminate one colour group, which I did easily as the colours didn't work together as well as the other piles.

I also decided that I would take the opportunity to dye some of the currently undyed fibres in my stash at the same time so that these would go into my "ingredients cupboard" for use at a later date.

So, what I will be dyeing in each dye pot is:

150-155g of Llandovery Whiteface Hill wool that I hand combed myself
40g Suri Alpaca, this is some raw fleece from an alpaca called "Butterscotch"
25g of 14.5 micron Merino, which was from Day 23 of the 2021 Advent Calendar
25g of Mulberry Silk
12g of Tussah Silk Noil
12g of Trilobal Nylon
12g Milk Protein, which was from Day 19 of the 2021 Advent Calendar

I soaked all of the fibres in warm water with a splash of Synthropol added to the water to remove any "chemical finish" that may have been added to the fibres during production.  This also removes any grease and dirt that may be left in the fleece.

I had intended my first batch to be dyed a kind of mustard yellow but I made a really stupid mistake when I was weighing the dye out and only realised once I added the fibres to the dye pot and saw the colour it all went.  Whoops, but a happy mistake because the fibres have turned out almost the exact colour I had intended for my second batch.

What I had planned was 1% dye depth made up of 95% Sunshine Yellow, 2.5% River Blue and 2.5% Flame Red.  What I should have weighed out was 2.62g of Sunshine Yellow and 0.138g each of River Blue and Flame Red.  What I actually weighed out was the correct amount of Sunshine Yellow and then I messed up and weighed out 1.38g each of River Blue and Flame Red (10 times too much of each colour).  The dye didn't take so well on the two Silk lots and in both cases they are kind of a peachy-coral colour along with what can only be described as grey and it looks like a pile of burnt rubbish.
