Hi,BONDOMAN !
I have found that the U.P. boxcar red by FLOQUILis an excellent color for NEW ships .Modified with a little REEFER WHITE it is great for a waterline color representing at least a couple of years in service.Now,for the GREENS , there,s a kettle of worms!
Ther are at least seven greens that can be used with TESTORS-MODEL MASTER BERET GREEN topping the list for new paint.Another is FLOQUIL GREEN (I don,t remember the proper name ,but it is a medium green ,close to ZINC CHROMATE , but , with less yellow in it .)
Blue is not a color seen often on large ships,but,it is used by some lines."CHESSIE BLUE" is perfect.The other color in this set is a" MODIFIED SKY BLUE" That,s achieved by taking FLOQUIL,S "CHESSIE BLUE and cutting it with"U.P. LIGHT FIELD GREY".
FLOQUIL colors are great for this and I too have been using them for years.Another favorite is the FLOQUIL color known as "AGED BRICK". --------TANKERbuilder
