I can't imagine the method names, either.

And thruthfully I'm not really sure how this should work.
<br>
I'm still very unsure about the lookuptable stuff ...

<blockquote type="cite">In fact if you build your own lookuptable,
and you put your own color in it, you are able to put color with alpha.
I do not remember exactly the method names. But then the alpha
transition might be smoother than the one you want.
<br>
For your example you can fill your lut with 4 color and set properly
the lut scalar range to behave as closely as you are expecting.
<br>
<br>
- blue+aplha=0.3
<br>
- green+aplha=0.7
<br>
- yellow+aplha=0.7
<br>
- red+alpha=1
<br>
<br>
Hope this could help...
