No, color can not be seen in the dark. The only color that can be seen in the dark is black, because it is dark. If it is not completely dark then you might be able to see the color of some objects.
Colors, also called hues, are generally described by two factors: value and intensity (or saturation). Value is how light or dark a hue is. Intensity is how bright or muted a hue is. Describing a color as "soft" is somewhat subjective. A "soft green" usually refers to a more muted hue. But for some a lighter value of the hue may seem "soft". Dark green would refer to adding black or another color that contains black to the original hue. A muted green could be dark or light.
