I have rechecked the NCS code for US Bermuda Beige RGB 233,211,199 (#E9D3C7) used in the 4:1 AAA Black Widow mix.
It is not NCS s0907-Y70R with a RGB of 234,221,216 (#EADDD8) commonly used outside the US for BW clones.
The closest match to US Bermuda Beige is NCS S1013-Y66R with a RGB value of 232,211,199 (#E8D3C7)
Don't just take my word for it. Doublecheck it yourself. There is an online NCS to RGB calculator available. I can't post links, yet, so google for ' mws-design NCS nach RGB Umrechnung '.
