Magnolia as a named color historically enjoyed sporadic support in web browsers. In Microsoft Internet Explorer 7 it may sometimes be rendered a pale magenta. In Mozilla Firefox 2.0 it may sometimes appear grayish pink.
In the UK, Magnolia paint is a neutral to warm white (as the petals in the picture of the plant), noted as being the 'standard' color of household paint, other than white. However, the color called "Magnolia" in UK paint is closer to peach rather than the rose-lavender white of the web color. It is a ubiquitous color which is available for most type of paint.
