I am looking over the instructions of the re-release of the Tamiya Renault 5 Turbo, and some of the paint codes have me confused. I got the past with 5 parts Flat Yellow to 2 parts Red, but this one stated as 'Blue (X-4) + Flat Base (X-21)' has me confused.

I know when Tamiya tells you to mix colors, but doesn't give a ratio, it's 1:1, but does Blue + Flat Base mean mix the two together, or simply apply the flat clearcoat over the blue?
