Is this 1953 Bowman Color Mantle legit?

[KCRfan1]

For me, something is not right about these cards for auction. I believe they are authentic, legit, original. However, the 54 Jackie Robinson card is very blue. The yellow background is pale comapred to the others on ebay. Look at other ebay auctions of this card and this is easily noticed. The 53 Mantle is the same way. His skin tone is blue, as is the Yankee cap. The overall card has a blueish tint. The 61 Mantle has no image or picture depth, and the image of Mantle himself looks washed out. The 53 Bowman looks the same to me. Take some time to look at each card the seller has for auction and compare his cards to the same that others have for sale. There is enough here that if a couple of cards cause me to be suspect, I should be suspect of his whole lot. I suspect either color retouching or the cards have been " cleaned " and the colors have been altered. My concern is if you would have the cards graded they would not grade and return as altered.
