That last command has 3 images in it as far as I can see!
Making it a three image masked composition!
Also composite is does not seem to understand all options.
However you can do a -blend compose in "convert" It just isn't as
straight forward.
The better idea however is to just colorize a rose image then overlay a
trimmed down original in the center.
convert rose: -fill red -colorize 25% \
\( rose: -shave 10x10 \) \
-gravity center -composite rose_blend.png
It isn't a blend, but it is a near equivelent. Less processing too.
This is very simular to 'self framing images'

Except that we are doing a red de-contrast inside the image rather than
adding an enlarged lower contrast copy of the image around the original.
I am however still not certain that is what the original requester is
wanting as it is a little unclear.
