Hue is circular in an HSV definition. Values near its two numeric endpoints can describe neighboring color-wheel positions.
Retain the hue convention
In a normalized HSV convention, hue travels around a color wheel and returns to the initial color at the interval endpoint. A wrapped selection therefore needs two numeric subintervals when it crosses that endpoint. The hue range, saturation and value remain distinct quantities in the representation. Primary reference: MathWorks HSV hue color wheel and range.
For an original color-selection worksheet, record the actual numeric hue convention. Do not assume another library uses the same endpoint scale. Keep a hue condition separate from any additional saturation or value conditions so the accepted color scope can be reconstructed.
Select a fictional wrapped interval
Define an invented normalized hue selection as h at least 0.95 or h at most 0.05, with 0 ≤ h < 1. The values 0.98 and 0.02 are both included, while 0.50 is excluded. Writing the single impossible condition 0.95 ≤ h ≤ 0.05 would instead accept nothing.
This teaching interval explicitly states inclusive limits and does not provide an approved packaging color tolerance. It only demonstrates how a circular interval crosses a numeric boundary. Equal hue selection also does not establish equal intensity, saturation or physical print color.
Review the intended color scope
Prepare an original color-wheel sketch with the interval and endpoint convention marked. Retain the converted sample values and any other channel conditions. If the numeric encoding changes, convert the interval meaning rather than copying only its endpoint numbers into the new system.
No hue range here certifies an HM color classifier. The reader decision is whether the selected circular region has been represented correctly by its numerical comparisons. Actual recognition needs application-specific image and color evidence beyond the wrapped-interval arithmetic.
Customer Questions
Are both fictional values 0.98 and 0.02 selected?
Yes, by the stated wrapped condition.
Is 0.50 selected?
No.
Can the interval be written as one reversed ascending range?
No. The stated condition uses the two endpoint regions.
