the tints seem to be practically perfect, and in the yellow and green not far from correct, but in the green they run a trifle toward the blue and in the yellow become a little gray or broken. But in the shades the black disk has done wonders for color instruction, particularly in making standard neutral grays which cannot be imitated by white and black pigments, and in determining the shades of yellow, as has been explained. See Page 36.
Therefore, after having shown actual tints and shades with the folded models, and perhaps the other materials suggested, place a colored disk combined with a white disk on the wheel, and in front of them a smaller colored disk of the same color as the larger one for comparison,, and by changing the relative proportions show various tints. Then substitute a black disk for the white and show shades. If, for example, orange is taken, all proportions of both tints and shades may be shown very truthfully, the deeper shades being very rich browns. Having in this way impressed on the children the terms tints and shades, give them the paper tablets, Selection No. 2, in the deepest tints and the lightest shades, reserving the lightest tints and deepest shades found in Selection No. 4 for later use.
Let each member of the class lay the spectrum in the normal colors and then select the six tints corresponding to the six standards. When all of them think they have done this, tell them to choose the corresponding shades. If a number fail in the attempt it may be well to set up three sizes of disks on the color wheel in shade, standard and tint of red. In showing a tint of red with the disks it is not a good plan to make a tint lighter than R. 95, W. 5, which is about R. T. 1. If the wheel is not available samples of papers may be held up in the three tones so that the class can get the correct idea. There is no best method of reaching all pupils in any class, but in some way at this point in color education every pupil ought to acquire such knowledge of the subject as to be able to select at least the six standard scales in three tones, and this should be
