Lower brightness scores indicate a darker image.
The dependent variable was represented by all the brightness scores calculated as the differences between the mean brightness values of white badge vs. background and white badge vs. body.
As expected, spectra that reflect low amounts of light (e.g., spectrum 3) have low brightness scores while those, such as spectrum 4, that reflect highly in part or all of the spectrum show high brightness values.
Ventral coloration was scored as PC1 in a principal component analysis of hue, saturation, and brightness scores from four ventral body regions (see " Methods" section) aDays after 30 April bAssuming unequal variances cNumbers are sums for the entire 2004 breeding season, i.e., including first and second broods.
Indeed, color transparency, brightness, and luminosity scores were significantly improved at T1 on the treated compared to the nontreated hemiface.
Note that, in this color scoring scheme, "brightness" is an indicator of how dark or light a color is and correlates closely with mean total reflectance (Montgomerie 2006; also see Fig. 1).
Joseph Colaneri conducted the many heavy martial parts of the score with crisp brightness, but the lighter parts got a little heavy.
From each family, five representative individuals were scored for their brightness values (B-values) using tools in Adobe Photoshop CS3.
At T1, the color scores (skin transparency, brightness and luminosity) were significantly improved on the treated compared to the nontreated hemiface (Table 2, Figures 3 and 4).
The creative team attempted to deliver that brightness first by filling out the score to make this an all-out musical.
