Pearl Beige is the standard interior color for pickup cabs in 1954.

All parts were Pearl Beige, except for the Steering wheel, steering column/mast-jacket, and 3-speed column-shifter mechanism.

The "CHEVROLET" letters on the dash were white, and there were black center sections on the dash vertical grill-bars to the left and right of the radio-grill bars.

Here is a Dupont Paint sheet for 1954.

Will you have a painted grill and bumpers? If so, ask, if you want color information (it's all on that paint link). Also, if you need paint codes, PPG can provide all the colors (information on colors, codes, and obtaining modern formulas/codes are available in this Tech Tip).
