If any of the visual classes DirectColor, PseudoColor or GrayScale is supported:
A call to xname obtains the closest available RGB values for the
.A colormap
argument  to those specified for the colour named
.A color
in the database, and stores those values in the read-write colourmap entry
specified by the
.M pixel
component of the
.S XColor
structure.
>>STRATEGY
For each visual class DirectColor, PseudoColor and GrayScale:
  Create a colormap with alloc set to AllocAll.
  Store the r,g and b colour values of XT_GOOD_COLOUR_NAME in the colourmap with XStoreNamedColor.
  Obtain the rbg values of the stored color with XQueryColor.
  Store those rgb values in the colormap with XStoreColor.
  Obtain the stored rgb values with XQueryColor.
  Verify the rgb values stored in the two cells are identical.

>>ASSERTION Good A
If any of the visual classes DirectColor, PseudoColor or GrayScale is supported:
A call to xname changes the red, green and blue values
in the read-write colourmap entry in accordance with the 
.A flags
argument.
>>STRATEGY
For each supported visual class DirectColor, PseudoColor and GrayScale:
  Create a colormap with XCreateColormap.
  Store XT_GOOD_COLOR_NAME r, g and b values in cell 0 with XStoreNamedColor.
  Obtain the r,g and b values with XQueryColor.
  Complement the rgb values and store the value in cell 0 with XStoreColor.
  Obtain the bitwise complemented rgb values using XQueryColor.
  For each possible combination DoRed, DoGreen and DoBlue in flags:
    Store the bitwise complementary rgb values in the same cell with XStoreColor.
    Store the XT_GOOD_COLOR_NAME values in the colourmap cell using XStoreNamedColor.
    Verify that only the components of the colourcell specified by the flags value have been altered with XQueryColor.
