Subject: Re: [Qgis-user] colorramp starting from white
Attached is an example image.
Currently it is very hard to distinguish lakes from areas in the lowest class, for example in the southwest area.
In the map at the right, I manually adjusted the color ramp to start at a light green color. Should that be the default?

Instead of changing manually, why not "Invert the Color ramp" when
applying it?

Am I the only one who would like the color ramps in QGIS to NOT start
from (super nearly) white, but from a light version of the color?
For example, "Reds" should go from (light) pink to red.
Currently, the first class in my legend always looks white, as many
other parts of my map often do. Therefore it is hard to see where my
data is and where not.
Another thing, changing it manually is hard because of the 7 stops in
the ramps.
I'm happy to figure this out and make a PR, but would like to know
other's opinions first.
Regards,
Raymond
