All ropes currently offered are only available in the exclusive version with the small trisken knots. 

The ropes are dyed throughout, including the knot, resulting in a relatively deep, though not completely, colorfast dye. High-quality textile dye is used to prevent any future bleeding. The color is well-fixed, allowing the ropes to be washed if necessary. However, I generally advise against machine washing, as this would severely damage the rope's structure. Instead, hand washing is preferable, and the ropes should be dried under tension. A damp cloth is still the best option. After washing, the ropes should definitely be treated with oil or wax.
