Previously, ten colour combinations were used:
{ background-color: #ff6; color: #000; }{ background-color: #aff; color: #000; }{ background-color: #9f9; color: #000; }{ background-color: #f99; color: #000; }{ background-color: #f6f; color: #000; }{ background-color: #800; color: #fff; }{ background-color: #0a0; color: #fff; }{ background-color: #860; color: #fff; }{ background-color: #049; color: #fff; }{ background-color: #909; color: #fff; }Lately however, the palette has been simplified and it now only has five colours:
{ background-color: #ff0; color: #000; }{ background-color: #0ff; color: #000; }{ background-color: #f0f; color: #000; }{ background-color: #7fff00; color: #000; }{ background-color: #1e90ff; color: #000; }Seeing is believing.
