Tamiya acrylic paint color substitution

[thewonderwaffle1]

Hello I am trying to build few 1/35 scale models. 3.7cm PaK 35/36 AT Gun, German Machine Gun Troops, 7.5cm PaK40/L46 AT Gun, M4A3 Sherman 75mm Gun Late Production.

I am wondering if there colors i can substitute for certain Tamiya acrylic paints such as:
XF-52 Flat Earth
XF-56 Metallic Gray*
XF-57 Buff
XF-59 Desert Yellow*
XF-62 Olive Drab
XF-63 German Gray
XF-65 Field Gray
XF-85 Rubber Black
X-10 Gun Metal*
X-10 Chrome Silver*
X-14 J.A. Gray

I found other colors such as Gold, Khaki, Brown, Gloss Black, Gloss Red, Red, White, and Black at my local art supply store, all not Tamiya acrylic paints.
Other colors such as Dark Green, Red Brown, Dark Yellow and few of the ones listed above with an asterisk, I found but didn't buy them since it looked liked their color was off.

I can't buy the paints on Tamiya USA website since it work take my credit card.

I never liked Tamiya paints, honestly. I worked at a hobby store for 6 years, and sold the stuff, but that was in the 80s and early 90s so things would have changed by now. I'd say there are a hundred different colors and names that you could try, but if you can't use a credit card on that site, maybe somewhere else? Hobby stores might have online sales sites. Obviously it would depend on where you are and what kind of credit card it is, whether they'd accept it.
