I would never have guessed that.
How about something like an enumeration that has a range of outputs options 
like:
KColorBlend::limitBlendOutput, KColorBlend::extremeBlendOutput, 
KColorBlend::accessibilityLowContrast; KColorBlend::accessibilityHighContrast
and so on. Then you use the right enumeration for the purpose you are trying 
to achieve.

The k value should be called blendFactor in the declaration.

This might also be better placed in the QColor code - have you submitted a 
wishlist item to the Trolls?
