Hello,
we have chosen wood-aluminum windows from Internorm. The exterior color will be RAL 7016 (Anthracite). The exterior windowsill is currently planned to be aluminum (also RAL 7016).
However, we are now considering switching the exterior windowsill to Helopal. It is said to look more high-quality, but what appeals to us more is that it is quieter in the rain. What are your thoughts on this?
And if Helopal, would you recommend—if available—sticking with RAL 7016 or choosing a neutral color that contrasts with the window?
Thank you

Well, I have the *noise* of raindrops on an aluminum window sill... I wouldn’t choose that again.Then there is a defect in the installation.N

When choosing beautiful wood-aluminum windows, it would be a shame to simply install aluminum window sills. Why not opt for attractive granite window sills instead? They look great, last forever, are easy to clean, and you won’t even hear hail on them (on the window sill). They come in numerous colors and finishes (polished is best).
Usually, anti-vibration mats are glued underneath (similar to Armaflex but with bitumen). It makes a night-and-day difference. Then you hear the rain more on the damp ground than on the window sill.
They were probably "forgotten" or simply not proactively requested or offered in @Nice-Nofret's case.

Usually, even well-installed aluminum window sills with anti-vibration coating, decoupling (e.g., rubber seals between the window and the sill, etc.), and appropriate substructure/fastening/thermal insulation still tend to be measurably and noticeably louder than stone window sills in direct comparison.
Much larger stone mass provides better sound insulation.
Note: Modern, well-installed, thick, and tight windows generally dampen external noise from the window sill significantly better than before, so it is not uncommon that you barely hear rain because of this alone.
