Can an enum make references to another enum?

I'm trying to figure out a compiler error.

I have an enum called ColorPalette which references a second enum called
ColorName. Here is a relevant excerpt from ColorName:

==============================================================
public enum ColorName {

    BLACK (new Color(0, 0, 0)),
    WHITE (new Color(255, 255, 255)),
    PALE_GRAY (new Color(204, 204, 204)),
    PALE_DULL_RED (new Color(255, 153, 153)),
        /* etc... */
    MEDIUM_FADED_RED (new Color(255, 51, 51));

    private final Color color;
    /**
     * Constructor for enum ColorName.
     *
     * @param color the color associated with the color name.
     */
    ColorName(Color color) {
        this.color = color;
    }

    public Color getColor() { return this.color; }
}

==============================================================

Here is an excerpt of ColorPalette which illustrates how I'm using
ColorName:

==============================================================
public enum ColorPalette {

    /** Constant and data for BLUES color palette. */
    BLUES (ColorName.PALE_GRAY, ColorName.WHITE, ColorName.BLACK,
ColorName.PALE_WEAK_BLUE, ColorName.PALE_DULL_BLUE,
ColorName.MEDIUM_FADED_BLUE, ColorName.PALE_DULL_ORANGE,
ColorName.RED_RED_PINK),

    /** Constant and data for REDS color palette. */
    REDS (ColorName.PALE_GRAY, ColorName.WHITE, ColorName.BLACK,
ColorName.PALE_DULL_RED, ColorName.MEDIUM_FADED_RED,
ColorName.DARK_FADED_RED, ColorName.PALE_DULL_TEAL,
ColorName.SPRING_SPRING_GREEN),

        /* etc.... */

    /** The background color associated with a given color palette. */
    private final ColorName backgroundColorName;

    /** The light text color associated with a given color palette. */
    private final ColorName textLightColorName;

    /** The dark text color associated with a given color palette. */
    private final ColorName textDarkColorName;

    /** The light contrast color associated with a given color palette.
*/
    private final ColorName contrastLightColorName;

    /** The medium contrast color associated with a given color palette.
*/
    private final ColorName contrastMediumColorName;

    /** The dark contrast color associated with a given color palette. */
    private final ColorName contrastDarkColorName;

    /** The opposite color associated with a given color palette. */
    private final ColorName oppositeColorName;

    /** The clash color associated with a given color palette. */
    private final ColorName clashColorName;

    /**
     * Constructor for enum ColorPalette.
     *
     * @param backgroundColor the background color associated with the
color palette.
     * @param textLightColor the light text color associated with the
color palette.
     * @param textDarkColor the dark text color associated with the color
palette.
     * @param contrastLightColor the light contrast color associated with
the color palette
     * @param contrastMediumColor the medium contrast color associated
with the color palette.
     * @param contrastDarkColor the dark contrast color associated with
the color palette.
     * @param oppositeColor the opposite color associated with the color
palette.
     * @param clashColor the clash color associated with the color
palette.
     */
    ColorPalette(ColorName backgroundColorName, ColorName
textLightColorName, ColorName textDarkColorName, ColorName
contrastLightColorName, ColorName contrastMediumColorName, ColorName
contrastDarkColorName, ColorName oppositeColorName, ColorName
clashColorName) {
        this.backgroundColorName = backgroundColorName;
        this.textLightColorName = textLightColorName;
        this.textDarkColorName = textDarkColorName;
        this.contrastLightColorName = contrastLightColorName;
        this.contrastMediumColorName = contrastMediumColorName;
        this.contrastDarkColorName = contrastDarkColorName;
        this.oppositeColorName = oppositeColorName;
        this.clashColorName = clashColorName;
    }

    /**
     * Gets the background color associated with a given ColorPalette.
     *
     * @return the background color associated with a given ColorPalette.
     */
    public Color getBackgroundColor() { return
this.backgroundColorName.getColor(); }

    /**
     * Gets the light text color associated with a given ColorPalette.
     *
     * @return the light text color associated with a given ColorPalette.
     */
    public Color getTextLightColor() { return
this.textLightColorName.getColor(); }

       /* etc... */

}
==============================================================

Every single reference to ColorName in ColorPalette is flagged with a
compile error: "ColorName cannot be resolved to a variable" in the
Constants section or "ColorName cannot be resolved to a type" elsewhere.
One of the fixes is to import ColorName but when I try this, nothing
happens, even though ColorPalette and ColorName reside in the same
package and ColorName has no compile errors.

What's going on here? I can't figure out why ColorName isn't "seen" by
ColorPalette even though both are public and in the same package.
