Minimal coloring and strength of graphs
Discrete Mathematics, 2000 A proper vertex coloring \(c\) of a graph \(G\) using colors \(1,2,\dots\) is said to be minimal if \(\sum_{v\in V(G)} c(v)\) is minimum among all vertex colorings of \(G\). The vertex strength of \(G\), denoted by \(s(G)\), is the smallest number of colors needed to obtain a minimal coloring of \(G\). (The edge strength of \(G\), denoted by \(s'(G)\),

Contrast Affects the Strength of Synesthetic Colors
Cortex, 2006 Grapheme-color synesthesia is an automatic, involuntary experience of seeing colors when viewing numbers, letters or words on a printed page. Previous research has demonstrated that synesthesia is a genuine perceptual phenomenon, but crucially, all of these experiments have used high-contrast letters and numbers.
