This is already a yellow based color how much warmer are you thinking . often it is just the light in the space that has an effect on the color so I guess maybe try changing the light bulbs to a warmer color in the spaces where you want warmer.

Thanks Patricia...Bulbs are 3000k.

These are similar in Value and Chroma to Wool Skein but move increasingly anti-clockwise towards the Yellow-Red Hue Family away from Wool Skein. Elmira White is also more neutral and the most likely to pull peachy/pink in its warmth.
