Color gradients that don't carry a qualitative bias?

I'm looking for a color gradient to visually denote a variable but without
the overloading of a 'good/bad' measure to it. Clearly Green->Red or
Green->Yellow->Red has an implied qualitative bias, and I've seen some
people use Blue->Yellow but that has some visibility issues (but is better
for the majority of colorblind users). Of course most spectra will present a
problem for someone (low-contrast in part of the spectrum or difficulty in
color differentiation), but I'm curious to see if anyone has good examples,
concrete or hypothetical, of alternatives.
Also, it's not a problem if one side of the gradient carries a 'more
important' connotation, so long as the other side has a 'less important'
rather than a 'worse' connotation.
