### Question:
Palette { public synchronized ColorModel getColorModel() throws IOException { if (colors != null) { final ColorModel candidate = colors.get(); if (candidate != null) { return candidate; } } return getImageTypeSpecifier().getColorModel(); } protected  Palette(final PaletteFactory factory, final String name,
                      final int numBands, final int visibleBand); synchronized ColorModel getColorModel(); abstract ImageTypeSpecifier getImageTypeSpecifier(); RenderedImage getImage(final Dimension size); @SuppressWarnings("deprecation") void show(); @Override int hashCode(); @Override boolean equals(final Object object);  }### Answer:
@Test public void testColorModel() throws IOException { final PaletteFactory factory = PaletteFactory.getDefault(); final Palette palette = factory.getPalettePadValueFirst("rainbow", 100); final IndexColorModel icm = (IndexColorModel) palette.getColorModel(); assertEquals(100, icm.getMapSize()); assertEquals(0, icm.getTransparentPixel()); }
