unibond colours

[sealantnovice]

i need to replace some of the selant on my upvc windows. i've seen the unibond selaants specifically for this but have a question about the colours.

they do Ice white and brilliant white,

i'm used to the normal white of bog standard selants but want to know what the two unibond ones look like, what exactly do they mean by ice white? and how does their brilliant white compare to standard bathroom sealant colours?
