COLOUR CLASSIFICATION
For the purpose of Colour Classification, all colours, shades, tints hues and combinations thereof found in the cultivated forms of the dahlia have been grouped in the following twelve divisions.
The predominant colour or colours determine colour Classification which appear on the face of the ray florets and in such classification the colour of the reverse of the ray florets is not generally taken into consideration. An exception is made in the case of certain orchid-flowered, pompon or ball dahlias. Cultivars classified in colour must not be exhibited in any other colour class other than that indicated in the alphabetical list of cultivars. Cultivars not included in this list may be shown in groups appropriate to their colour.
In the case of blended, bi-colours or variegated cultivars the first colour indicated is the dominant colour, and such cultivars may be exhibited in classes for blooms of their dominant colour except where separate classes for blended and/or bicoloured and/or variegated cultivars are included in the show schedule.
