TABLE SHOWING PERCENTAGES OF NEUTRAL GRAY
IN THE BROKEN COLOR SCALES.
Every Plate in each series of broken colors (′ to ′′′) contains exactly the same percentage of neutral gray in each color, the relative amount increasing progressively in the several series, as shown in the following table. The percentages of white in the tints and of black in the shades of the tone scales are in all cases exactly the same as in the tone scales of pure colors.
| Series. | Percentages. | |
|---|---|---|
| Color. | Neutral Gray. | |
| Pure Colors | 100 | |
| (′) | 68 | 32 |
| (′′) | 42 | 58 |
| (′′′) | 23 | 77 |
| (′′′′) | 10 | 90 |
| (′′′′′) | 4.5 | 95.5 |
| Neutral Gray | 100 | |

Note.—The percentages given in the preceding tables may not in all cases be precisely those actually contained in the colors on the Plates, since absolute precision in reproduction is hardly possible. All that can be claimed is a reasonably close approximation to the ideal.
