If the clothes are all in pale colors, then a quilted item made with additional fabric in a bolder contrasting color might not be in keeping with the deceased person's personality or choice of colors and might not remind the person receiving the quilt of the loved one very much even if it does contain the used fabric. Maybe you should stick to the soft pale colors because that was the colors that were sent to you. That may very well be the colors that are associated with the loved one. Or perhaps you might want to ask about adding colors that are different than the color palette that you received. Just a suggestion.
