Sorry  I think of the green component as adding Yellow to red.  Reduce 
the green component on other words.  It needs to be a cooler cleaner red

How about a darker red?  Try using some media, maybe an absorption or a
scattering with added absorption, with a completely transparent pigment and
a finish with some specular highlight and variable reflection.  That should
give a much more realistic result then simply having the surface colored red
(especially if volume is going to vary).  Remember that blood is pretty
dense in its red coloring so the media colors should be multiplied fairly
high.  It doesn't take much blood before the color drops to almost black,
wheras only thin smears produce that bright red.

Maybe a bit more specular and/or less roughness.  It looks like solid red
candle wax or plastic at the moment.  It needs to be shinier imo.

Maybe to much transmit. What if you set transmit to zero? and lower 
filter a bit? Also, adding media atenuation and some scattering may 
help. As it is now, the transmit plus filter adds up to 1.2, the net 
result is an intensification of any ray passing thrue it. Normaly, you 
want to keep filter + transmit < 1.

His color is:

color rgbft <0.27255,0,0, 0.8, 0.4>
or
color red 0.27255 green 0 blue 0 filter 0.8 transmit 0.4
                   ^^^^^^^
Please explain how he could reduce the green level more! ;-)

My main problem is with the stain itself, not the texture.  in a few spots, we 
can see the underside of the spheres used to make the stain itself.  Not good.

Ooops  I misread the .8 as being the green component.

Well I was trying to ge a driped pool,  so when I saw his stock shape I just
flatened it and got aprox. what I wanted, as it stands this is what I'm
useing, because I can't find anything that I like better......I also don't
know how to modify the is thing :-).
#declare blood=
isosurface {
function{
f_sphere(x, y, z, 1.8) - (-f_snoise3d(x*1.5, y*1, z*1)*2.25)
}contained_by { sphere {<0,0,0>, -3.3 } }
accuracy 0.003
max_gradient 5
scale 0.5
texture{pigment{
color rgbft <0.27255,0,0, 0.8, 0.4>}}
rotate<0,20,0>
translate <-0.2, 1.3, 0>
scale <2,2,0.05> scale 2.0 translate -1.25*z};

Why shouldn't you try a spheres blob?
