29 * ColourSchemeProperty binds names to hardwired colourschemes and tries to deal
30 * intelligently with mapping unknown names to user defined colourschemes (that
31 * exist or can be created from the string representation of the colourscheme
32 * name - either a hex RGB triplet or a named colour under java.awt.color ). The
33 * values of the colourscheme constants is important for callers of
34 * getColourName(int i), since it can be used to enumerate the set of built in
35 * colours. The FIRST_COLOUR and LAST_COLOUR symbols are provided for this.
40 public class ColourSchemeProperty
44 * Returns a colour scheme for the given name, with which the given data may
45 * be coloured. The name may be one of
50 * <li>Hydrophobic</li>

54 * <li>Strand Propensity</li>

63 * <li>an AWT colour name e.g. red</li>
64 * <li>residue colours list e.g. D,E=red;K,R,H=0022FF;c=yellow</li>
66 * If none of these formats is matched, the string is converted to a colour
67 * using a hashing algorithm.
