Added Ink or Ink-like products

A recent question came to me about other products I might use for colors other than included in Tsukineko's 45 bottled ink line.  Know first that I LOVE Tsukinekos inks.  I do acknowledge I'd be an even happier gal with a warm yellow in the line.
Hope this is somewhat helpful :

As to OTHER PRODUCTS  you might like to try... I've included a photo showing the following left to right.. 

• I have played with  Acrylic Inks by FW, and  Dr Martins Bombay Pigmented India Ink   
• I haven't played with Speedball inks  but would give those a try.(not shown in photo) 
• I've played a wee bit with Dupont Inks though I'm not clear there is a wide range of colors... I've seen these on silk where  color/value was fantastic.
• I know some who really like INKtense by Derwent .. though they apply differently beginning as a watersoluble pencil
• Airbrush inks like Creatix,,, I believe there are many transparent airbrush inks that might be  winners
• Some like Jacquard DyeNaFlow
• Golden Airbrush Colors
• Golden Acrylic "Fluid" 
• I often use  Pebeo (thinned w water)  Setacolor Transparent paint ... usually for "wash"  or "glaze" like efforts rather than detail. Have attached a photo as reference

In markers, I sometimes use a pigment ink pen (when I can find) ZIG
