No, the color RAM needs to be replaced seperatly due to the way it's hooked up the VIC (D8 - D11). That means it's read in parallel with the other RAM. You can either find another 2114 or LC3514A (still easy enough to get) or use a 6116 (see C128 schematics for the general idea) or any other available SRAM that's at least 4 Bit wide and 1K deep. Just tie all unused address lines to GND and the unused data lines (D4 to D7) to +5V using resistors (they used 3.3KOhm in the C128).
