1. An image processing device for creating corrected image data by correcting object image data, the image processing device comprising: a controller configured to execute: determining a representative value which represents specific pixels in the object image data, each of the specific pixels having a hue within a particular range of hue, the representative value being a coordinate value in a color space of an orthogonal coordinate system; determining a target value based on the representative value and a degree of correction designated by a user, the target value being a coordinate value in the color space of the orthogonal coordinate system; and correcting a value of each particular pixel included in the object image data such that the value of the each particular pixel approaches the target value, wherein the each particular pixel is included in a surrounding area of the representative value, in a case where a coordinate value in the color space of the orthogonal coordinate system of a correction target pixel is identical to the representative value, the correcting of the value of each particular pixel includes correcting the coordinate value in the color space of the orthogonal coordinate system of the correction target pixel into a first coordinate value that is between the representative value and the target value, and in a case where the coordinate value in the color space of the orthogonal coordinate system of the correction target pixel is a second coordinate value that is between the representative value and the target value, the correcting of the value of each particular pixel includes correcting the coordinate value in the color space of the orthogonal coordinate system of the correction target pixel into a third coordinate value that is between the first coordinate value and the target value.
