The ramps that go from white to color (just 2 colors - for example
white/green) have more stops than needed. I would just delete the
intermediate stops and set the first to the pale green of your choice.
Then save your new color ramp for future use.
For maximum contrast between high and low data values, you could leave
it as white/green and then set the screen/page background color to
something other than the default white. Go to Project-Properties and
then Background Color.

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?

Hi Raymond,
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
