Both Prime color schemes

[Voldemar]

Last month I bought one for a gift to a relative who graduated from high school. It was with a high contrast keys. My Prime also has a high contrast keys. Interesting, I put both Prime calculators side by side, there was a small difference in key coloring. The latest calculator was with a slightly less intense orange color. The difference was noticeable. I conclude, for Prime calculators the color of the keys may vary slightly.
