Illustration above shows minimum range of body dilution (red) which will be lightened by the dun gene.

Illustration above shows maximum range of body dilution (red) which will be lightened by the dun gene. Please note that dun dilution cannot create shapes other than sticking to the "hard points" of the legs as shown here and should not create isolated dark areas resembling the points marking.

Illustration above shows minimum range of primitive markings which consists of a dorsal stripe on the back (blue).

Illustration above shows maximum range of dorsal stripe, shoulder barring, knee stripes and forehead cobwebbing (blue).

Body dilution has a soft gradient only, smooth with no texture. It can fade softly out at the edges. 

Dorsal stripe and barring may be hard edges or somewhat soft edged. They can be a mixture with dorsal stripe and barring having different edges. The edges of the primitive markings can fade out. Shoulder barring will always be oriented towards the Rukaan's shoulder.

The diluted body area will be a lighter version of the base coat. It cannot be more saturated than the base coat, and can only be white if it is on a white base coat. It can be slightly lighter, or substantially lighter than what they sit over. Body dilution area can have nuance but it should not resemble pangare, roan or points too greatly. 

The dorsal stripe and barring will be a darker version of the base coat. They cannot be black unless they are on a black base coat. They will always be be slightly or moderately darker than what they sit over.

Please note that layer effects (such as screen, soft light, overlay, etc) in image editing software may change the saturation or color of your markings. If you are using non-standard layers, please check your saturation and hue before submitting to make sure they are consistent with the design guides.
