I agree that chandeliers are way too yellow.
You can change the color of the chandelier by going to the files at AppData\Roaming\Vintagestory\assets\survival\blocktypes\metal then selecting chandelier and changing the lightHsvByType setting. For Example I made mine the same color as lanterns.
lightHsvByType: {
"chandelier-candle0": [7, 3, 0],
The third number is the brightness level. chandeliers have nine different brightness levels depending on the number on candles, starting at zero.
