Correcting An Irregular Over Dye Project

Well I didn't dye this piece to begin with but I have and occasionally do dye work. in this case, I bought this over dyed 100% cotton upholstery fabric that I wish to turn into a quilted gift table runner piece.... BUT... after I got it home, I found the over dye was most irregular in one corner so what to do? First for perspective,,, the original background for this piece was a soft blue and pale yellow. You see a bit of the yellow here and there. Here's one section of the already dyed fabric.

Well I 'm a bit mad at myself for not photographing the irregular area BEFORE I started this fix effort.... but here is the back side of the irregular area where some rather strong blue still resides.

There were choices on how to fix:
a. over dye again ( a bit challenging unless you dye all the time and can predict the value outcome. Also a big setup/cleanup project)
b. Overdye with inks.... I could do it in a method similar to item c. ...... It's just that ink all and all for big backgrounds is a little more costly than item c below.
c. 'Paint' the heavily water-misted background with a slightly watered mixture of matching transparent paint ( ala Pebeo Setacolor transparent). So that's what I did.... followed by drying/ heat setting using a dry iron on a cotton setting. Heat setting makes it permanent. Whoala!! Done in minutes!!!!

It's now ready to be prepped for quilting.
