An article from the Master Weaver bulletin (March 1957) introducing a rule-based method for choosing colour schemes in handweaving. It explains hue, value and chroma using the Munsell notation, and names four colours (A, D, W, Z) by area and contrast. Three tables are used to select hues, values and chromas, and worked examples show how to adjust a scheme when a colour is unavailable in the sample cards. It is the first in a planned series on colour, pattern and texture.
