Yup, back in the day when engineers designed calculators for other engineers to use in their daily work, h/p played very close attention to the color coding of the keys and visibility in low light levels. Now calculators are designed for kids in school--which in itself is even farther from the 'real world' than when the h/p 35 came on the scene--and the 'design' is left to people who might never have used a calculator.

I'd bet a Prime that the silver was the result of a desire to make it differ from the high-end TI calculators' all-black look.
