2 Prologue This is the story of Mister Chrome who started out to paint his home. The paint ran out when half away through so to the store he quickly flew to buy some more of matching hue, a delicate shade of egg-shell blue. But when he tried this latest batch, he found it simply didn’t match. No wonder he was in a fix, for of the colors we can mix, the major shades and those between, ten million different can be seen
You foolish man said missis chrome you should have taken from the home a simple of the color done you cant remember every one. Taking care that she had got a sample from the early pot, she went and bought her husband more of better color from the store Before she paid, she checked the shade, and found a perfect match it made.

2 You foolish man, said Missis Chrome, you should have taken from the home a simple of the color done; you can’t remember every one. Taking care that she had got a sample from the early pot, she went and bought her husband more of better color from the store. Before she paid, she checked the shade, and found a perfect match it made. In triumph now she took it home, and gave it straight to Mister Chrome. He put it on without delay, and found the color now okey
But, after dark, in tungsten light they found the color still not right. So to the store they both went now, with samples clear, and as ked them how a paint that matched in daylight bright could fail to match in tungsten light The man's reply to their complaint was that the pigments in the paint had been exchanged, since they had bought for others of a different sort To solve the problem on their wall, he gave them paint to do it all from just one batch of constant shade and then at last success was made

To compensate them for their trouble, the store sent to them curtains double They hung them up with great delight; they matched in tungsten and daylight. A neighbor then did make a call and fixed his eye upon the wall; the paint, he said was all one color, but clearly saw the curtains duller Though colors strange at times appear, the moral of this tale is clear. to understand just what we see, object, light, and eye, all three must color all our thin king through of chromic problems, old or new
2 To compensate them for their trouble, the store sent to them curtains double. They hung them up with great delight; they matched in tungsten and daylight. A neighbor then did make a call and fixed his eye upon the wall; the paint, he said was all one color, but clearly saw the curtains duller! Though colors strange at times appear, the moral of this tale is clear: to understand just what we see, object, light, and eye, all three, must color all our thinking through of chromic problems, old or new!
