Translation of "Fundamentally" in Dutch

This is fundamentally wrong.

Dit is fundamenteel verkeerd.

Red is fundamentally more distinct than the other colors.

Rood is fundamenteel meer apart dan de ander kleuren.

After I had thought about this elementary question fundamentally, I came to the conclusion that the difference, which is often described as "considerable" or "substantial" by distinguished people, between the indispensable words "important" and "essential" isn't significant, but rather is irrelevant.

Nadat ik over deze elementaire vraag grondig had nagedacht, kwam ik tot de conclusie dat het verschil tussen de onmisbare woorden 'belangrijk' en 'essentiëel', welke vaak beschreven wordt als 'aanzienlijk' of 'degelijk' door voorname mensen, niet belanrijk is, maar eerder irrelevant.
