Perhaps the florist attaches more importance to the colour than to the form of the flowers he uses in his business. As a rule, flowers with clear and distinct shades of colour are most appreciated; while those with confused tones or lacking in brilliancy are practically useless. A colour that will not show up well at nighttime under gas-light or electric light is of little use, because a good deal of the florist's art is seen under these conditions.
